Struct TextCoordinates 

pub struct TextCoordinates { /* private fields */ }

A checked conversion index containing Unicode scalar boundaries only.

Implementations

impl TextCoordinates

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

pub fn new_budgeted( text: &str, budget: &MemoryBudget, poll: &mut dyn FnMut() -> AnalysisResult<()>, ) -> AnalysisResult<Budgeted<Self>>

Construct a scalar index with caller-owned byte limits and cancellation. ASCII needs no boundary buffer; other input reserves one entry per scalar and its end boundary.

pub fn utf8_len(&self) -> usize

pub fn utf16_len(&self) -> usize

pub fn utf8_to_utf16(&self, offset: usize) -> AnalysisResult<usize>

pub fn utf16_to_utf8(&self, offset: usize) -> AnalysisResult<usize>

pub fn offsets(&self, utf8: Range<usize>) -> AnalysisResult<SourceOffsets>

pub fn covering_offsets_utf16( &self, utf16: Range<usize>, ) -> AnalysisResult<SourceOffsets>

Retain exact UTF-16 coordinates and cover split surrogate pairs in UTF-8.

An empty range inside a pair covers that scalar; an empty range at a scalar boundary remains empty.
