Struct unicode_bidi::InitialInfoExt

pub(crate) struct InitialInfoExt<'text> {
    pub(crate) base: InitialInfo<'text>,
    pub(crate) flags: Vec<ParagraphInfoFlags>,
}

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), and whether any bidi isolation controls are present.

Implementations

impl<'text> InitialInfoExt<'text>

pub fn new_with_data_source<'a, D: BidiDataSource>( data_source: &D, text: &'a str, 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.

Trait Implementations

impl<'text> Debug for InitialInfoExt<'text>

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

Formats the value using the given formatter.

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

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

Tests for self and other values to be equal, and is used by ==.

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

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