Struct zng_ext_font::TextSegment

pub struct TextSegment {
    pub kind: TextSegmentKind,
    pub level: BidiLevel,
    pub end: usize,
}

Represents a single text segment in a SegmentedText.

Fields

kind: TextSegmentKind

Segment kind.

level: BidiLevel

Direction of the segment in the context of other segments of the line.

end: usize

Exclusive end index on the source text.

The segment range starts from the end of the previous segment, or 0, e.g: prev_seg.end..self.end.

Implementations

impl TextSegment

pub fn direction(self) -> LayoutDirection

Direction of the glyphs in the segment.

Segments iterate in the logical order, that is, the order the text is typed. If two segments in the same line have direction RTL they must be layout the first to the right of the second.

Trait Implementations

impl Clone for TextSegment

fn clone(&self) -> TextSegment

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TextSegment

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

Formats the value using the given formatter.

impl PartialEq for TextSegment

fn eq(&self, other: &TextSegment) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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