Struct ShapedGlyphData

pub(crate) struct ShapedGlyphData {
    count: usize,
    buffer: *mut hb_buffer_t,
    glyph_infos: *mut hb_glyph_info_t,
    pos_infos: *mut hb_glyph_position_t,
}

Fields

count: usize

buffer: *mut hb_buffer_t

glyph_infos: *mut hb_glyph_info_t

pos_infos: *mut hb_glyph_position_t

Implementations

impl ShapedGlyphData

unsafe fn new(buffer: *mut hb_buffer_t) -> ShapedGlyphData

Create a new ShapedGlyphData from the given HarfBuzz buffer.

Safety

• Passing an invalid buffer pointer to this function results in undefined behavior.
• This function takes ownership of the buffer and the ShapedGlyphData destroys the buffer when dropped so the pointer must an owned pointer and must not be used after being passed to this function

Trait Implementations

impl Drop for ShapedGlyphData

fn drop(&mut self)

Executes the destructor for this type.

impl HarfBuzzShapedGlyphData for ShapedGlyphData

fn entry_for_glyph(&self, i: usize, y_pos: &mut Au) -> ShapedGlyphEntry

Returns shaped glyph data for one glyph, and updates the y-position of the pen.

fn len(&self) -> usize

The number of shaped glyphs

fn byte_offset_of_glyph(&self, i: usize) -> u32

The byte offset of the shaped glyph in the souce text
