Struct LineMap 

pub struct LineMap { /* private fields */ }

Line map for efficient offset <-> position conversion. Stores the starting offset of each line.

Implementations

impl LineMap

pub fn build(source: &str) -> Self

Build a line map from source text.

pub fn offset_to_position(&self, offset: u32, source: &str) -> Position

Convert a byte offset to a Position (line, character). Character is counted in UTF-16 code units for LSP compatibility.

pub fn position_to_offset( &self, position: Position, source: &str, ) -> Option<u32>

Convert a Position (line, character) to a byte offset.

pub const fn line_count(&self) -> usize

Get the number of lines.

pub fn line_start(&self, line: usize) -> Option<u32>

Get the starting offset of a line.

Trait Implementations

impl Clone for LineMap

fn clone(&self) -> LineMap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineMap

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

Formats the value using the given formatter.
