Struct InitialInfo

pub struct InitialInfo<'text> {
    pub text: &'text [u16],
    pub original_classes: Vec<BidiClass>,
    pub paragraphs: Vec<ParagraphInfo>,
}

Initial bidi information of the text (UTF-16 version).

Contains the text paragraphs and BidiClass of its characters.

Fields

text: &'text [u16]

The text

original_classes: Vec<BidiClass>

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

paragraphs: Vec<ParagraphInfo>

The boundaries and level of each paragraph within the text.

Implementations

impl<'text> InitialInfo<'text>

pub fn new(text: &[u16], 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.

pub fn new_with_data_source<'a, D: BidiDataSource>( data_source: &D, text: &'a [u16], 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)

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 InitialInfo<'text>

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

Formats the value using the given formatter.

impl<'text> PartialEq for InitialInfo<'text>

fn eq(&self, other: &InitialInfo<'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.
