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

Implementations

impl IncrementalParserV2

pub fn new() -> Self

Create a parser with default reuse configuration and no cached tree.

pub fn with_reuse_config(config: ReuseConfig) -> Self

Create parser with custom reuse configuration

pub fn edit(&mut self, edit: Edit)

Queue an edit to be applied on the next parse call.

pub fn parse(&mut self, source: &str) -> ParseResult<Node>

Parse source, reusing cached tree nodes where edits did not affect them.

pub fn get_metrics(&self) -> &IncrementalMetrics

Get current performance metrics

pub fn reset_metrics(&mut self)

Reset performance metrics

pub fn get_last_reuse_analysis(&self) -> Option<&ReuseAnalysisResult>

Get the last reuse analysis result if available

pub fn set_reuse_config(&mut self, config: ReuseConfig)

Update reuse configuration

pub fn used_advanced_reuse(&self) -> bool

Check if the last parse used advanced reuse analysis

pub fn get_reuse_efficiency_report(&self) -> String

Get detailed reuse efficiency report

Trait Implementations

impl Default for IncrementalParserV2

fn default() -> Self

Returns the “default value” for a type.
