👋 Overview

RSaPar is a Rust library for schema-based parsing and validation of structured data files, inspired by JSaPar for Java.

💻 Usage

To use RSaPar, you need to define a ParserConfig and then call the parser() method.

Here's a step-by-step guide on how to get started:

1. Add RSaPar to your project with:

   cargo add rsapar

2. Define the data schema: Create a schema XML file (schema.xml) to describe the structure of your data. The schema format attempts to follow the same rules as JSaPar's schema format. Detailed documentation on the support and compatibility with the JSaPar schema format in RSaPar will be provided soon. An example schema can be found in the example folder.

3. Configure the parser: Set up the parser configuration with the path to your data file, the number of workers, and the path to your schema file.

   Example:

   let config = crate::ParserConfig {
       file_path: "./example/fixedwidth_data.txt".to_string(),
       file_schema: "./example/fixedwidth_schema.xml".to_string(),
   };
   
   let mut parser = Parser::new(config).unwrap();
   
   for line_result in parser.iter_mut() {
       match line_result {
           Ok(processed_line) => println!("{:?}", processed_line),
           Err(processed_line) => println!("Error processing line: {:?}", processed_line),
       }
   }

This setup provides a brief overview of how to start using RSaPar. The schema structure is inspired by JSaPar, and more information on this alignment will be available in the future.

🚀 Roadmap

• Full support for validation of fixed-width files (v0.1.2)
