PositionedGlyphC

Struct PositionedGlyphC 

Source
#[repr(C)]
pub struct PositionedGlyphC { pub glyph_id: u32, pub x: f32, pub y: f32, pub advance: f32, pub cluster: u32, }
Expand description

C-ABI compatible positioned glyph.

This struct matches the layout expected by external renderers like Cairo:

  • glyph_id: Index into the font’s glyph table
  • x, y: Position in user space (typically pixels)
  • advance: Horizontal advance width
  • cluster: Cluster index for text segmentation (useful for cursor positioning)

§Size and Alignment

This struct is 20 bytes with 4-byte alignment on all platforms.

Fields§

§glyph_id: u32

Glyph index in the font (maps to cairo_glyph_t.index)

§x: f32

Horizontal position in user space

§y: f32

Vertical position in user space

§advance: f32

Horizontal advance width

§cluster: u32

Cluster index (maps to original text position)
