Struct ContextDetector 

pub struct ContextDetector { /* private fields */ }

Detects the context or domain of functions based on naming patterns and file location.

The detector uses compiled regexes to identify common function naming conventions (e.g., format_*, parse_*, handle_*) and file path patterns to classify functions into domain-specific contexts.

Performance

Creating a new ContextDetector compiles 17 regexes. For repeated use, prefer the ContextDetector::global() singleton to avoid recompilation.

Example

use debtmap::analysis::context_detection::ContextDetector;
use std::path::Path;

let detector = ContextDetector::global();
let analysis = detector.detect_context(&function, Path::new("src/parser.rs"));
println!("Context: {:?}, confidence: {}", analysis.context, analysis.confidence);

Implementations

impl ContextDetector

pub fn new() -> Self

Creates a new context detector with compiled regex patterns.

Compiles 17 regexes for pattern matching. For hot paths, prefer ContextDetector::global() to reuse a singleton instance.

pub fn global() -> &'static Self

Get the global singleton instance.

This avoids repeated regex compilation when called from hot paths. The singleton is lazily initialized on first access.

pub fn detect_context( &self, function: &FunctionMetrics, file_path: &Path, ) -> ContextAnalysis

Detect the context of a function

Trait Implementations

impl Default for ContextDetector

fn default() -> Self

Returns the “default value” for a type.
