pub struct LineAnnotationMap { /* private fields */ }

Maps each source line to the annotation regions covering it.

Implementations

impl LineAnnotationMap

pub fn build_from_regions(regions: &[RegionRef], total_lines: usize) -> Self

Build the map from regions and the total number of source lines.

pub fn regions_at_line(&self, line: u32) -> &[usize]

Get region indices covering a given line (1-indexed).

pub fn next_annotated_line(&self, from: u32) -> Option<u32>

Find the next line >= from (1-indexed) that has annotation coverage. Returns None if no annotated lines from that point.

pub fn prev_annotated_line(&self, from: u32) -> Option<u32>

Find the previous line <= from (1-indexed) that has annotation coverage.

Trait Implementations

impl Debug for LineAnnotationMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result
