Struct ShapedBuffer 

pub struct ShapedBuffer { /* private fields */ }

A buffer of shaped and positioned glyphs. This is the final output of a text shaping operation.

Implementations

impl ShapedBuffer

pub fn new( glyphs: Vec<ShapedGlyph>, lines: Vec<LineInfo>, width: f32, height: f32, ) -> Self

Creates a new empty ShapedBuffer.

pub fn glyphs(&self) -> &[ShapedGlyph]

Returns the list of shaped glyphs in this buffer.

pub fn lines(&self) -> &[LineInfo]

Returns the tracked line information for this buffer.

pub fn len(&self) -> usize

Returns the number of glyphs in the buffer.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no glyphs.

pub fn content_size(&self) -> (f32, f32)

Returns the logical width and height of the text content itself (no padding).

pub fn outer_size(&self, padding: &Padding) -> (f32, f32)

Returns the visual width and height including the provided padding.

pub fn size(&self) -> (f32, f32)

Returns the logical (width, height) used during the last shaping pass. This is an alias for content_size().

pub fn index_at(&self, x: f32, y: f32) -> usize

Finds the character byte index closest to the given (x, y) coordinates.

pub fn position_at(&self, index: usize) -> Option<(f32, f32)>

Returns the (x, y) coordinates for a given character byte index.
