Struct icu_capi::bidi::ffi::BidiParagraph

pub struct BidiParagraph<'info>(pub Paragraph<'info, 'info>);

Bidi information for a single processed paragraph

Tuple Fields

0: Paragraph<'info, 'info>

Implementations

impl<'info> BidiParagraph<'info>

pub fn set_paragraph_in_text(&mut self, n: usize) -> bool

Given a paragraph index n within the surrounding text, this sets this object to the paragraph at that index. Returns nothing when out of bounds.

This is equivalent to calling paragraph_at() on BidiInfo but doesn’t create a new object

pub fn direction(&self) -> BidiDirection

The primary direction of this paragraph

pub fn size(&self) -> usize

The number of bytes in this paragraph

pub fn range_start(&self) -> usize

The start index of this paragraph within the source text

pub fn range_end(&self) -> usize

The end index of this paragraph within the source text

pub fn reorder_line( &self, range_start: usize, range_end: usize, out: &mut DiplomatWrite, ) -> Option<()>

Reorder a line based on display order. The ranges are specified relative to the source text and must be contained within this paragraph’s range.

pub fn level_at(&self, pos: usize) -> u8

Get the BIDI level at a particular byte index in this paragraph. This integer is conceptually a unicode_bidi::Level, and can be further inspected using the static methods on Bidi.

Returns 0 (equivalent to Level::ltr()) on error
