Struct HarfbuzzGlyphShapingResult 

pub(crate) struct HarfbuzzGlyphShapingResult {
    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 HarfbuzzGlyphShapingResult

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

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
