Struct zng_ext_font::TextOverflowInfo

pub struct TextOverflowInfo {
    pub line: usize,
    pub text_char: usize,
    pub included_glyphs: SmallVec<[Range<usize>; 1]>,
    pub suffix_origin: Point2D<f32, Px>,
}

Info about a shaped text overflow in constraint.

Can be computed using ShapedText::overflow_info.

Fields

line: usize

First overflow line.

All segments in this line and next lines are fully overflown. The previous line may be partially overflown, the lines before that are fully visible.

Is the ShapedText::lines_len if the last line is fully visible.

text_char: usize

First overflow character in the text.

Note that if overflow is not wrapping (single text line) the char may not cover all visible glyphs in the line if it is bidirectional.

included_glyphs: SmallVec<[Range<usize>; 1]>

Glyphs not overflown in the last not overflown line.

If the line is not bidirectional this will be a single range covering the not overflow glyphs, if it is bidi multiple ranges are possible due to bidi reordering.

suffix_origin: Point2D<f32, Px>

Placement of the suffix (ellipses or custom).

The suffix must be of the width given to ShapedText::overflow_info and the same line height as the text.

Trait Implementations

impl Clone for TextOverflowInfo

fn clone(&self) -> TextOverflowInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextOverflowInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TextOverflowInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TextOverflowInfo

fn eq(&self, other: &TextOverflowInfo) -> 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.

impl Serialize for TextOverflowInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
