Struct IncrementalParserV2 

pub struct IncrementalParserV2 {
    pub reused_nodes: usize,
    pub reparsed_nodes: usize,
    pub metrics: IncrementalMetrics,
    pub last_reuse_analysis: Option<ReuseAnalysisResult>,
    /* private fields */
}

High-performance incremental parser with intelligent AST node reuse

Maintains previous parse state and applies edits incrementally when possible, falling back to full parsing for complex structural changes. Designed for real-time editing scenarios with sub-millisecond update targets.

Thread Safety

IncrementalParserV2 is not thread-safe and should be used from a single thread. For multi-threaded scenarios, create separate parser instances per thread.

Fields

reused_nodes: usize

reparsed_nodes: usize

metrics: IncrementalMetrics

last_reuse_analysis: Option<ReuseAnalysisResult>

Performance tracking for reuse analysis
