Errors

Returns an error if the file cannot be read.

pub fn extract_batch( &mut self, matches: &[MatchLocation], ) -> Vec<Result<ContextLines>>

Extract context for multiple matches, grouping by file for efficiency

Returns context for each match in the same order as input.

pub fn extract_grouped( &mut self, matches: &[MatchLocation], ) -> Vec<GroupedContext>

Extract grouped context for multiple adjacent matches in same file

Merges overlapping context windows into continuous ranges.

pub fn clear_cache(&mut self)

Clear the file cache

pub fn cache_size(&self) -> usize

Get current cache size
