Struct TextFormatterImpl 

pub struct TextFormatterImpl;

The text formatter.

Internal upstream; public so that the Skia unit tests reach it.

Implementations

impl TextFormatterImpl

pub fn new() -> Self

pub fn split_text_runs_with_length( text_runs: &[Rc<dyn TextRun>], length: i32, object_pool: &FormattingObjectPool, ) -> (SplitResult<RentedList<Rc<dyn TextRun>>>, i32)

Split a sequence of runs into two segments at specified length. The actual length of the first segment (which may differ from length when the split lands on a cluster boundary) is returned as the second value. This lets the wrap caller avoid a separate second pass to sum run lengths.

pub fn create_empty_text_line( first_text_source_index: i32, paragraph_width: f64, paragraph_properties: &Rc<dyn TextParagraphProperties>, ) -> Rc<TextLineImpl>

Creates an empty text line.

Trait Implementations

impl TextFormatter for TextFormatterImpl

fn format_line( &self, text_source: &dyn ITextSource, first_text_source_index: i32, paragraph_width: f64, paragraph_properties: &Rc<dyn TextParagraphProperties>, previous_line_break: Option<&Rc<TextLineBreak>>, ) -> Option<Rc<dyn TextLine>>

Formats a text line.

fn format_line_with_cache( &self, text_source: &dyn ITextSource, first_text_source_index: i32, paragraph_width: f64, paragraph_properties: &Rc<dyn TextParagraphProperties>, previous_line_break: Option<&Rc<TextLineBreak>>, text_run_cache: Option<&TextRunCache>, ) -> Option<Rc<dyn TextLine>>

Formats a text line, optionally using a TextRunCache to avoid redundant shaping.
