Trait TreeSitterRule 

pub trait TreeSitterRule: Send + Sync {
    // Required methods
    fn name(&self) -> &'static str;
    fn supported_languages(&self) -> &'static [Language];
    fn check(&self, file: &ParsedFile) -> Vec<CodeIssue>;

    // Provided methods
    fn skips_test_files(&self) -> bool { ... }
    fn check_with_context(
        &self,
        file: &ParsedFile,
        _is_test_file: bool,
        _context: &FileContext,
        _config: &ProjectConfig,
    ) -> Vec<CodeIssue> { ... }
}

A code quality rule that analyzes source files using tree-sitter AST.

Unlike the original [crate::rules::Rule] trait which requires syn::File, this trait works on tree-sitter’s language-agnostic CST. Rules declare which languages they support via supported_languages.

Required Methods

fn name(&self) -> &'static str

Unique identifier for this rule (e.g. "deep-nesting").

fn supported_languages(&self) -> &'static [Language]

Languages supported by this rule.

fn check(&self, file: &ParsedFile) -> Vec<CodeIssue>

Analyze a parsed file and return detected issues.

Provided Methods

fn skips_test_files(&self) -> bool

Whether to skip test files (default: true).

fn check_with_context( &self, file: &ParsedFile, _is_test_file: bool, _context: &FileContext, _config: &ProjectConfig, ) -> Vec<CodeIssue>

Analyze a file with additional context about the file’s role in the project. Override this when the rule needs to adjust behavior based on file context (e.g. skipping UI files, relaxing thresholds for examples) or config.
