Advanced node reuse analyzer with sophisticated matching algorithms

Fields

analysis_stats: ReuseAnalysisStats

Statistics for reuse analysis

Implementations

impl AdvancedReuseAnalyzer

pub fn new() -> Self

Create a new reuse analyzer with default configuration

pub fn with_config(_config: ReuseConfig) -> Self

Create analyzer with custom configuration

pub fn analyze_reuse_opportunities( &mut self, old_tree: &Node, new_tree: &Node, edits: &EditSet, config: &ReuseConfig, ) -> ReuseAnalysisResult

Analyze potential node reuse between old and new trees

Returns a mapping of old node positions to reuse strategies, enabling intelligent tree reconstruction with maximum node reuse.

pub fn map_old_position_to_new(&self, old_pos: usize, edits: &EditSet) -> usize

Map an old-tree byte position to its corresponding position in the new tree, using the supplied EditSet to apply byte shifts.

Semantics:

• If old_pos precedes the first edit’s start_byte, returns old_pos unchanged.
• If old_pos falls inside an edit’s old range [start_byte, old_end_byte), returns that edit’s new_end_byte (i.e. the position is consumed by the edit and snaps to the edit’s new boundary).
• Otherwise the position is shifted by the cumulative byte shift of all prior edits whose old_end_byte <= old_pos.

Edits in EditSet are sorted by start_byte, so iteration short- circuits as soon as the next edit starts past old_pos.

pub fn try_register_match( &self, reuse_map: &mut HashMap<usize, ReuseStrategy>, old_pos: usize, new_pos: usize, reuse_type: ReuseType, confidence: f64, ) -> bool

Attempt to register an old_pos -> new_pos reuse claim, enforcing the one-to-one invariant: at most one old position may map to any given new position.

Returns true if the registration was inserted, false if some other old_pos has already claimed the same new_pos (in which case the existing claim is left unchanged).

Trait Implementations
