CodeGraph Parser API

Shared trait and types for building CodeGraph language parsers.

This crate provides the foundation for implementing language parsers that work with the CodeGraph database. It defines:

CodeParser trait: The core interface all parsers must implement
Entity types: Language-agnostic representations of code elements (functions, classes, etc.)
Relationship types: Representations of code dependencies (calls, imports, etc.)
Configuration: Customizable parser behavior
Metrics: Performance and success tracking
Error handling: Comprehensive error types

Example

use codegraph_parser_api::{CodeParser, ParserConfig, ParserError, FileInfo};
use codegraph::CodeGraph;
use std::path::Path;

struct MyParser {
    config: ParserConfig,
}

impl CodeParser for MyParser {
    fn language(&self) -> &str {
        "mylang"
    }

    fn file_extensions(&self) -> &[&str] {
        &[".my"]
    }

    fn parse_file(&self, path: &Path, graph: &mut CodeGraph) -> Result<FileInfo, ParserError> {
        // Implementation here
        todo!()
    }

    fn parse_source(&self, source: &str, file_path: &Path, graph: &mut CodeGraph)
        -> Result<FileInfo, ParserError> {
        // Implementation here
        todo!()
    }

    fn config(&self) -> &ParserConfig {
        &self.config
    }

    fn metrics(&self) -> ParserMetrics {
        ParserMetrics::default()
    }

    fn reset_metrics(&mut self) {
        // Reset internal metrics
    }
}
