Struct IncrementalParser 

Source 
pub struct IncrementalParser { /* private fields */ }
Expand description

Incremental parsing optimizer.

Tracks changed regions to determine which AST nodes need reparsing.

Implementations§

Source§

impl IncrementalParser

Source

pub fn new() -> IncrementalParser

Create a new incremental parser with no changed regions

Source

pub fn mark_changed(&mut self, start: usize, end: usize)

Mark a region as changed.

Overlapping regions are automatically merged.

Source

pub fn needs_reparse(&self, node_start: usize, node_end: usize) -> bool

Check if a node needs reparsing based on changed regions.

Returns true if the node overlaps with any changed region.

Source

pub fn clear(&mut self)

Clear all changed regions.

Call after reparsing to reset the change tracking.
