CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.

Walkthrough

The changes in this pull request introduce a new library, qbg, into the Rust project by modifying several Cargo.toml files and adding new source files. The workspace Cargo.toml is updated to include the qbg library, while the Cargo.toml for the algorithm library adds a dependency on qbg. A new Cargo.toml file is created for the qbg library, specifying its dependencies and metadata. Additionally, new source files (build.rs, input.cpp, input.h, lib.rs) are added to implement functionality related to QBG construction and indexing.

rust/libs/algorithm/Cargo.toml (1)

25-25: Documentation needed for QBG integration

Since this is a draft PR introducing a new algorithm component, please provide:

  1. Description of what QBG is and its purpose
  2. Integration requirements and dependencies
  3. Any performance implications or considerations

Consider adding these details to:

  • PR description
  • README in the QBG module
  • Code documentation
rust/libs/algorithms/qbg/src/input.h (2)

32-39: Add parameter names to set_qbg_construction_parameters for clarity

Including parameter names in the function declaration enhances readability and helps developers understand the purpose of each parameter.


49-65: Include parameter names in set_qbg_build_parameters function

Providing parameter names in the function declaration improves code comprehension and maintainability.

rust/libs/algorithms/qbg/src/lib.rs (5)

59-62: Inconsistent Integer Types in set_hierarchical_clustering_init_mode

The function set_hierarchical_clustering_init_mode uses i16 for the parameter hierarchical_clustering_init_mode, whereas similar parameters in other functions use i32. Consider using consistent integer types to avoid potential issues.


63-65: Type Mismatch in set_number_of_second_objects

The parameter number_of_second_objects in set_number_of_second_objects is of type u32, while other similar parameters use usize. For consistency and to prevent potential bugs, consider using usize here as well.


109-130: Use Meaningful Values in Test Property Setters

In the test test_qbg, many property setters are assigned the value 1. Using more realistic and diverse values can improve the effectiveness of the test by covering a wider range of scenarios.


184-185: Simplify Return Statements in Test Functions

The lines return Ok(()); can be simplified to just Ok(()) for brevity and idiomatic Rust code.

Also applies to: 216-217


84-85: Clarify Parameter Naming and Types in new_index and new_prebuilt_index

The new_index function takes a Pin<&mut Property> as the second parameter named p, while new_prebuilt_index takes a bool named p. This overloading of p with different types may cause confusion. Consider renaming the boolean parameter to something more descriptive, like prebuilt, for clarity.

rust/libs/algorithms/qbg/src/input.cpp (2)

315-328: Missing Error Handling in Factory Functions

The factory functions new_index and new_prebuilt_index do not handle exceptions that may be thrown during object creation, potentially leading to unhandled exceptions.

Consider using exception handling to capture and report any errors during object creation:

std::unique_ptr<Index> new_index(const rust::String &path, Property &p)
{
    try
    {
        return std::make_unique<Index>(path, p);
    }
    catch (const std::exception &e)
    {
        // Handle exception, possibly log the error
        std::cerr << "Error creating Index: " << e.what() << std::endl;
        return nullptr;
    }
}

227-238: Use of const char* Instead of std::string in open_index

Passing cpath.c_str() may lead to issues if cpath goes out of scope before c_str() is used.

Since cpath is a local variable, it's safe here, but consider passing std::string directly if the underlying function accepts it, to reduce unnecessary conversions.

24-24: LGTM! The workspace member addition follows project conventions.

The new qbg algorithm library is properly placed alongside other algorithm implementations (ngt, faiss).


24-24: Verify qbg library setup

Let's verify that the qbg library directory exists and has the required Cargo.toml configuration.

✅ Verification successful

QBG library setup is properly configured

The verification shows that the qbg library is correctly set up with:

  • Directory structure present at rust/libs/algorithms/qbg/
  • Required files: Cargo.toml, build.rs, and src/ directory
  • Proper Cargo.toml configuration with:
    • Package metadata
    • Required dependencies (anyhow, cxx)
    • Build dependencies (cxx-build, miette)
🏁 Scripts executed

The following scripts were executed for the analysis:

#!/bin/bash
# Description: Verify qbg library structure and configuration

# Check if the directory exists
if [ ! -d "rust/libs/algorithms/qbg" ]; then
    echo "Error: qbg directory does not exist at expected path"

25-25: Verify QBG integration path and dependencies

The dependency path looks consistent with other algorithm dependencies, but let's verify the integration.

✅ Verification successful

QBG dependency path and integration verified

The QBG integration appears to be properly structured:

  • QBG directory exists at the correct path (rust/libs/algorithms/qbg)
  • The library implements a C++ bridge for QBG index construction and search
  • Proper license headers and version metadata are present
  • No direct usage in algorithm lib yet, which is expected for a draft PR

273-273: Incorrect Use of v.length() in append

The use of v.length() may be incorrect if v does not have a length() method or if it does not return the expected size.

Verify that v.length() correctly returns the number of elements in the slice. If not, use v.size() or adjust accordingly.

Run the following script to check for the correct method to retrieve the size of rust::Slice:

Ensure that the correct method is consistently used across the codebase.

✅ Verification successful

Let's search for actual usage patterns of rust::Slice in the codebase to understand how it's being used and what methods are available. I've also included a search for the specific vector construction pattern to see the surrounding context.


Use of v.length() is correct for rust::Slice

Looking at the codebase usage, v.length() is the correct method for rust::Slice. This is evidenced by its usage in qbg/src/input.cpp and supported by the fact that rust::Slice is a Rust-C++ bridge type where the Rust convention for getting collection size is length(). The code correctly constructs a vector from the slice's iterators and uses length() to get its size.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for the correct method to get size from rust::Slice in the codebase.

# Search for usage of rust::Slice methods
rg --type-add 'cpp' --files-with-matches 'rust::Slice' | xargs grep -E 'rust::Slice.*\.(length\(\)|size\(\))' -A 2

    let path = "invalid/path".to_string();
    let mut p = Property::new();
    p.init_qbg_construction_parameters();

    // Test invalid dimensions
    p.set_dimension(0);
    assert!(Index::new(&"index".to_string(), &mut p).is_err());

The destructor is currently commented out, which could lead to resource leaks. The index should be properly closed when the object is destroyed.


335-348: LGTM! Well-implemented factory functions.

The factory functions make good use of modern C++ practices with std::unique_ptr for automatic memory management.

23-30: Add const correctness to getter methods.

The getter methods should be marked as const since they don't modify the object's state.

Apply this diff to improve const correctness:

-    rust::u32 get_id() { return id; }
-    rust::f32 get_distance() { return distance; }
+    rust::u32 get_id() const { return id; }
+    rust::f32 get_distance() const { return distance; }

59-75: Improve parameter documentation for set_qbg_build_parameters.

The method has many parameters with only partial documentation. Consider adding detailed parameter descriptions or using a parameter struct for better organization.

Example documentation format:

/**
 * Sets the QBG build parameters
 * @param init_mode Hierarchical clustering initialization mode
 * @param first_objects Number of objects for first level
 * ...
 */
void set_qbg_build_parameters(...);

1-22: LGTM! License and includes are properly set up.

The license header is complete, and all necessary includes are present.


94-94: Replace void *index with a specific pointer type.

Using void * reduces type safety and can lead to errors.


112-114: LGTM! Factory functions are well-designed.

The use of std::unique_ptr for factory functions follows modern C++ best practices and ensures proper resource management.


1-114: Verify Rust FFI integration and usage patterns.

Let's ensure the Rust side correctly uses this C++ interface.

✅ Verification successful

FFI integration is properly implemented and safe

The C++ interface is correctly integrated with Rust through CXX bridge with proper memory management:

  • Uses cxx::bridge for safe FFI bindings
  • Proper use of UniquePtr for C++ object lifetime management
  • Safe wrapper implementations in Rust modules (property and index)
  • Comprehensive test coverage validating the integration
  • Type-safe conversions between Rust and C++ types

96-102: Add safety documentation for the search function.

The search function handles raw data and should include documentation about:

  • Valid parameter ranges (k, radius, epsilon)
  • Input vector requirements (size, alignment)
  • Performance implications

Add documentation:

/// Searches the index for nearest neighbors.
///
/// # Arguments
/// * `v` - Query vector. Must have the same dimension as indexed vectors
/// * `k` - Number of nearest neighbors to return. Must be > 0
/// * `radius` - Search radius. Use 0.0 for unlimited radius
/// * `epsilon` - Error tolerance for approximate search
///
/// # Returns
/// Vector of (id, distance) pairs for the k nearest neighbors
fn search(
    self: Pin<&mut Index>,
    v: &[f32],
    k: usize,
    radius: f32,
    epsilon: f32,
) -> UniquePtr<CxxVector<SearchResult>>;

19-31: LGTM! Constructor and destructor properly manage memory.

The Property class correctly handles memory allocation in the constructor and cleanup in the destructor.


233-236: ⚠️ Potential issue

Uncomment and implement the destructor.

The destructor is commented out, which could lead to resource leaks. The index needs to be properly closed when the object is destroyed.

 Index::~Index()
 {
-    // close_index();
+    close_index();
 }

Likely invalid or redundant comment.


155-158: ⚠️ Potential issue

Fix type inconsistency in number_of_second_objects parameter.

The method uses rust::u32 while other similar methods use rust::usize. This inconsistency could lead to integer overflow issues on 64-bit systems when handling large datasets.

-void Property::set_number_of_second_objects(rust::u32 number_of_second_objects)
+void Property::set_number_of_second_objects(rust::usize number_of_second_objects)
 {
     qbg_build_parameters->number_of_second_objects = number_of_second_objects;
 }

461-475: 🛠️ Refactor suggestion

Add assertions to verify search results.

The test prints search results without verifying their correctness. Add assertions to validate:

  • Result ordering (by distance)
  • Distance values are non-negative
  • Number of results matches k
         let distances: Vec<f32> = search_results
             .pin_mut()
             .into_iter()
             .map(|s| s.get_distance())
             .collect();
-        println!("ids:\n{:?}", ids);
-        println!("distances:\n{:?}", distances);
+        assert_eq!(ids.len(), K, "Wrong number of results");
+        assert!(distances.iter().all(|&d| d >= 0.0), "Negative distances found");
+        assert!(distances.windows(2).all(|w| w[0] <= w[1]), "Results not ordered by distance");

400-720: Enhance test coverage and assertions

The test implementations primarily verify basic functionality but lack comprehensive assertions and error case testing.

Add the following improvements to tests:

  1. Verify search result ordering:
// In test_index()
let search_results = index.search(vec.as_slice(), K, RADIUS, EPSILON)?;
assert!(
    search_results.windows(2).all(|w| w[0].1 <= w[1].1),
    "Search results should be ordered by distance"
);
  1. Add error case testing:
#[test]
fn test_index_error_cases() -> Result<()> {
    let mut index = Index::new("nonexistent_path", &mut Property::new())?;
    assert!(index.get_object(999999).is_err(), "Should error on invalid ID");
    Ok(())
}
  1. Test parameter validation:
#[test]
#[should_panic(expected = "dimension must be positive")]
fn test_invalid_dimension() {
    let mut p = Property::new();
    p.set_qbg_construction_parameters(1, 0, 1, 1, 1, 1, 1);
}

175-178: Improve method naming consistency.

The method name set_number_of_subvectors_for_bp breaks the naming convention used by other setter methods. Consider renaming it to set_number_of_subvectors_build_params for consistency.

19-25: Consider using smart pointers for better memory safety.

Replace raw pointers with std::unique_ptr to prevent memory leaks and ensure automatic cleanup:

 class Property {
 private:
-    QBGConstructionParameters *qbg_construction_parameters;
-    QBGBuildParameters *qbg_build_parameters;
+    std::unique_ptr<QBGConstructionParameters> qbg_construction_parameters;
+    std::unique_ptr<QBGBuildParameters> qbg_build_parameters;
 public:
     Property() {
-        qbg_construction_parameters = new QBGConstructionParameters();
-        qbg_build_parameters = new QBGBuildParameters();
+        qbg_construction_parameters = std::make_unique<QBGConstructionParameters>();
+        qbg_build_parameters = std::make_unique<QBGBuildParameters>();
         qbg_initialize_construction_parameters(qbg_construction_parameters.get());
         qbg_initialize_build_parameters(qbg_build_parameters.get());
     }

210-420: Refactor error handling to reduce code duplication.

The error handling pattern is repeated across multiple methods. Consider extracting it into a helper function:

private:
    template<typename F>
    auto handle_error(F&& func) {
        NGTError err = ngt_create_error_object();
        auto result = func(err);
        if (!result) {
            string s = ngt_get_error_string(err);
            ngt_destroy_error_object(err);
            std::cerr << "Error: " << __func__ << std::endl;
            std::cerr << s << std::endl;
            throw std::runtime_error(s);
        }
        ngt_destroy_error_object(err);
        return result;
    }

Usage example:

void Index::save_index() {
    handle_error([this](NGTError err) {
        return qbg_save_index(index, err);
    });
}

336-388: 🛠️ Refactor suggestion

Use RAII for resource management in search method.

The current implementation could leak resources if an error occurs between allocations and deallocations. Use RAII to ensure proper cleanup:

 std::unique_ptr<std::vector<SearchResult>> Index::search(rust::Slice<const rust::f32> v, rust::usize k, rust::f32 radius, rust::f32 epsilon)
 {
     QBGQuery query;
     qbg_initialize_query(&query);
     std::vector<float> vec(v.begin(), v.end());
     query.query = vec.data();
     query.number_of_results = k;
     query.radius = radius;
     query.epsilon = epsilon;

+    struct ResourceGuard {

+        NGTObjectDistances results;
+        ~ResourceGuard() {

+    };
