Struct WrappedLineLayout 

pub struct WrappedLineLayout {
    pub unwrapped_layout: Arc<LineLayout>,
    pub wrap_boundaries: SmallVec<[WrapBoundary; 1]>,
    pub wrap_width: Option<Pixels>,
}

A line of text that has been wrapped to fit a given width.

Fields

unwrapped_layout: Arc<LineLayout>

The line layout, pre-wrapping.

wrap_boundaries: SmallVec<[WrapBoundary; 1]>

The boundaries at which the line was wrapped.

wrap_width: Option<Pixels>

The width of the line, if it was wrapped.

Implementations

impl WrappedLineLayout

pub fn len(&self) -> usize

The length of the underlying text, in utf8 bytes.

pub fn width(&self) -> Pixels

The width of this line, in pixels, whether or not it was wrapped.

pub fn size(&self, line_height: Pixels) -> Size<Pixels>

The size of the whole wrapped text, for the given line_height. can span multiple lines if there are multiple wrap boundaries.

pub fn ascent(&self) -> Pixels

The ascent of a line in this layout

pub fn descent(&self) -> Pixels

The descent of a line in this layout

pub fn wrap_boundaries(&self) -> &[WrapBoundary]

The wrap boundaries in this layout

pub fn font_size(&self) -> Pixels

The font size of this layout

pub fn runs(&self) -> &[ShapedRun]

The runs in this layout, sans wrapping

pub fn index_for_position( &self, position: Point<Pixels>, line_height: Pixels, ) -> Result<usize, usize>

The index corresponding to a given position in this layout for the given line height.

See also Self::closest_index_for_position.

pub fn closest_index_for_position( &self, position: Point<Pixels>, line_height: Pixels, ) -> Result<usize, usize>

The closest index to a given position in this layout for the given line height.

Closest means the character boundary closest to the given position.

See also LineLayout::closest_index_for_x.

pub fn position_for_index( &self, index: usize, line_height: Pixels, ) -> Option<Point<Pixels>>

Returns the pixel position for the given byte index.

Trait Implementations

impl Debug for WrappedLineLayout

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

Formats the value using the given formatter.

impl Default for WrappedLineLayout

fn default() -> Self

Returns the “default value” for a type.
