Trait LanguageAnalyzer 

pub trait LanguageAnalyzer: Send + Sync {
    // Required methods
    fn file_extensions(&self) -> &[&str];
    fn parse_file(
        &self,
        path: &Path,
        source: &str,
        config: &AnalysisConfig,
    ) -> Result<Vec<CodeUnit>, Box<dyn Error + Send + Sync>>;

    // Provided method
    fn is_test_code(&self, unit: &CodeUnit) -> bool { ... }
}

Trait for language-specific code analysis.

Implementors provide file-extension detection and parsing logic, allowing dupes-core to work with any language.

Test code handling: Analyzers should set CodeUnit::is_test to true for test functions, test modules, etc. The crate::analyze function will filter them out when Config::exclude_tests is enabled, using [is_test_code].

Required Methods

fn file_extensions(&self) -> &[&str]

File extensions this analyzer handles (without the leading dot).

fn parse_file( &self, path: &Path, source: &str, config: &AnalysisConfig, ) -> Result<Vec<CodeUnit>, Box<dyn Error + Send + Sync>>

Parse a single source file into code units.

path is the file’s location (for diagnostics), source is the file content, and config carries min-node / min-line thresholds.

Analyzers should tag test code via CodeUnit::is_test rather than filtering it out; the caller handles exclusion.

Provided Methods

fn is_test_code(&self, unit: &CodeUnit) -> bool

Check whether a code unit represents test code.

The default implementation delegates to CodeUnit::is_test, which language analyzers set during parsing.
