Struct TraceCollector 

pub struct TraceCollector { /* private fields */ }

Collects trace entries during transpilation.

Thread-safe collector that can be passed through the pipeline stages.

Examples

use decy_core::trace::{TraceCollector, TraceEntry, DecisionType, PipelineStage};

let mut collector = TraceCollector::new();
assert!(collector.is_empty());

collector.record(TraceEntry {
    stage: PipelineStage::CodeGeneration,
    source_location: None,
    decision_type: DecisionType::TypeMapping,
    chosen: "i32".to_string(),
    alternatives: vec!["i64".to_string()],
    confidence: 1.0,
    reason: "C int maps to Rust i32".to_string(),
});

assert_eq!(collector.len(), 1);
let json = collector.to_json();
assert!(json.contains("i32"));

Implementations
