Struct LineIndex 

pub struct LineIndex { /* private fields */ }

Precomputed line-start offsets for O(log n) position conversion.

Implementations

impl LineIndex

pub fn new(text: &str) -> Self

Build a line index from document text. O(n) in text length.

pub fn offset_to_position(&self, offset: usize) -> Position

Convert a byte offset to an LSP Position. O(log n) via binary search.

pub fn position_to_offset(&self, pos: Position) -> usize

Convert an LSP Position to a byte offset. O(1).

pub fn span_to_range(&self, start: usize, end: usize) -> Range

Convert byte offset span to an LSP Range.

Trait Implementations

fn clone(&self) -> LineIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineIndex

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

Formats the value using the given formatter.
