Struct BidiContext

pub struct BidiContext { /* private fields */ }

Implementations

impl BidiContext

pub fn new() -> Self

pub fn base_level(&self) -> Level

pub fn set_reorder_non_spacing_marks(&mut self, reorder: bool)

When reorder is set to true, reordering will apply rule L3 to non-spacing marks. This is likely more desirable for terminal based applications than it is for more modern GUI applications that feed into eg: harfbuzz.

pub fn runs<'a>(&'a self) -> impl Iterator<Item = BidiRun> + 'a

Produces a sequence of BidiRun structs that represent runs of text and their direction (and level) across the entire paragraph.

pub fn line_runs( &self, line_range: Range<usize>, ) -> impl Iterator<Item = BidiRun>

Given a line_range (a subslice of the current paragraph that represents a single wrapped line), this method resets whitespace levels for the line boundaries, and then returns the set of runs for that line.

pub fn reordered_runs(&self, line_range: Range<usize>) -> Vec<ReorderedRun>

pub fn reorder_line(&self, line_range: Range<usize>) -> (Vec<Level>, Vec<usize>)

line_range indicates a contiguous range of character indices in the paragraph set via resolve_paragraph. This method returns the reordered set of indices for display purposes.
