Using Visual Studio Code with Bazel

These instructions assume familarity with the use of Rust with Visual Studio Code in general and so include Salus specific configuration.

Configure Rust Analyzer

This provides for definition lookups, navigation, etc:

Add the following JSON to .vscode/tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Generate rust-project.json",
            "command": "bazel",
            "args": [
                "run",
                "@rules_rust//tools/rust_analyzer:gen_rust_project"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "group": "build",
            "problemMatcher": [],
            "presentation": {
                "reveal": "never",
                "panel": "dedicated",
            },
            "runOptions": {
                "runOn": "folderOpen"
            }
        },
    ]
}

Override check tool

Since the default cargo check behaviour is not available with Bazel a custom script provides substitute functionality

Add the following to your .vscode/settings.json

{
    "rust-analyzer.checkOnSave.overrideCommand": [
        "scripts/rust-analyzer-check.sh"
    ]
}
