Struct unicode_bidi::utf16::InitialInfoExt

source ·
struct InitialInfoExt<'text> {
    base: InitialInfo<'text>,
    flags: Vec<ParagraphInfoFlags>,
}
Expand description

Extended version of InitialInfo (not public API).

Fields§

§base: InitialInfo<'text>

The base InitialInfo for the text, recording its paragraphs and bidi classes.

§flags: Vec<ParagraphInfoFlags>

Parallel to base.paragraphs, records whether each paragraph is “pure LTR” that requires no further bidi processing (i.e. there are no RTL characters or bidi control codes present).

Implementations§

source§

impl<'text> InitialInfoExt<'text>

source

pub fn new_with_data_source<'a, D: BidiDataSource>( data_source: &D, text: &'a [u16], default_para_level: Option<Level>, ) -> InitialInfoExt<'a>

Find the paragraphs and BidiClasses in a string of text, with a custom BidiDataSource for Bidi data. If you just wish to use the hardcoded Bidi data, please use InitialInfo::new() instead (enabled with tbe default hardcoded-data Cargo feature)

http://www.unicode.org/reports/tr9/#The_Paragraph_Level

Also sets the class for each First Strong Isolate initiator (FSI) to LRI or RLI if a strong character is found before the matching PDI. If no strong character is found, the class will remain FSI, and it’s up to later stages to treat these as LRI when needed.

impl<'text> PartialEq for InitialInfoExt<'text>

source§

fn eq(&self, other: &InitialInfoExt<'text>) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
