Implementations

impl Bidi

pub fn create() -> Box<Bidi>

Creates a new Bidi from locale data using compiled data.

pub fn create_with_provider( provider: &DataProvider, ) -> Result<Box<Bidi>, DataError>

Creates a new Bidi from locale data, and a particular data source.

pub fn for_text_utf8<'text>( &self, text: &'text DiplomatStr, default_level: Option<u8>, ) -> Option<Box<BidiInfo<'text>>>

Use the data loaded in this object to process a string and calculate bidi information

Takes in a Level for the default level, if it is an invalid value or None it will default to Auto.

Returns nothing if text is invalid UTF-8.

pub fn for_text_valid_utf8<'text>( &self, text: &'text str, default_level: Option<u8>, ) -> Box<BidiInfo<'text>>

Use the data loaded in this object to process a string and calculate bidi information

Takes in a Level for the default level, if it is an invalid value it will default to LTR

pub fn reorder_visual(&self, levels: &[u8]) -> Box<ReorderedIndexMap>

Utility function for producing reorderings given a list of levels

Produces a map saying which visual index maps to which source index.

The levels array must not have values greater than 126 (this is the Bidi maximum explicit depth plus one). Failure to follow this invariant may lead to incorrect results, but is still safe.

pub fn level_is_rtl(level: u8) -> bool

Check if a Level returned by level_at is an RTL level.

Invalid levels (numbers greater than 125) will be assumed LTR

pub fn level_is_ltr(level: u8) -> bool

Check if a Level returned by level_at is an LTR level.

Invalid levels (numbers greater than 125) will be assumed LTR

pub fn level_rtl() -> u8

Get a basic RTL Level value

pub fn level_ltr() -> u8

Get a simple LTR Level value
