Module rust 

Rust dependency extractor using tree-sitter AST traversal.

Extracts use declarations and pub use re-exports from Rust source files, producing RustImportInfo and ExportInfo records for the dependency graph. Supports:

• Simple imports: use std::collections::HashMap;
• Nested imports: use std::collections::{HashMap, HashSet};
• Wildcard imports: use module::*;
• Aliased imports: use std::io::Result as IoResult;
• Crate-relative: use crate::core::Engine;
• Super-relative: use super::utils;
• Self-relative: use self::types::Config;
• Re-exports: pub use types::Config;, pub(crate) use internal::Helper;

Examples

use thread_flow::incremental::extractors::rust::RustDependencyExtractor;
use std::path::Path;

let extractor = RustDependencyExtractor::new();
let source = "use std::collections::HashMap;\nuse crate::config::Settings;";
let imports = extractor.extract_imports(source, Path::new("src/main.rs")).unwrap();
assert_eq!(imports.len(), 2);

Performance

Target: <5ms per file extraction. Tree-sitter parsing and AST traversal operate in a single pass without backtracking.

Structs

ExportInfo

Information extracted from a Rust pub use re-export.

RustDependencyExtractor

Extracts Rust import and export dependencies using tree-sitter AST traversal.

RustImportInfo

Information extracted from a single Rust use declaration.

Enums

ExtractionError

Errors that can occur during Rust dependency extraction.

Visibility

Visibility level of a Rust re-export (pub use).
