}
Expand description

Initial bidi information of the text.

Contains the text paragraphs and BidiClass of its characters.

Fields§

§text: &'text str

The text

§original_classes: Vec<BidiClass>

The BidiClass of the character at each byte in the text. If a character is multiple bytes, its class will appear multiple times in the vector.

§paragraphs: Vec<ParagraphInfo>

The boundaries and level of each paragraph within the text.

Implementations§

source§

impl<'text> InitialInfo<'text>

source

pub fn new(text: &str, default_para_level: Option<Level>) -> InitialInfo<'_>

Find the paragraphs and BidiClasses in a string of text.

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.

The hardcoded-data Cargo feature (enabled by default) must be enabled to use this.

source

pub fn new_with_data_source<'a, D: BidiDataSource>( data_source: &D, text: &'a str, default_para_level: Option<Level> ) -> InitialInfo<'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.
