Struct ShapedGlyph 

pub struct ShapedGlyph {
    pub gid: u16,
    pub x_advance: f32,
    pub y_advance: f32,
    pub x_offset: f32,
    pub y_offset: f32,
    pub cluster: u32,

    pub unsafe_to_break: bool,
}

A glyph produced by the shaper.

Fields

gid: u16

Glyph ID in the font.

x_advance: f32

Horizontal advance in pixels (scaled by font size).

y_advance: f32

Vertical advance (usually 0.0 for LTR text).

x_offset: f32

Horizontal offset from the cursor position.

y_offset: f32

Vertical offset from the baseline.

cluster: u32

Index into the source string (UTF-8 byte offset of cluster start).

is_whitespace: bool

true if this glyph represents whitespace (space, tab, newline).

Layout engines use this to distinguish trimmable trailing whitespace and to compute expandable gaps for justified text.

unsafe_to_break: bool

true if breaking a line before this glyph is unsafe because the glyph is part of a multi-glyph cluster (e.g. a ligature or a mark attached to a base glyph). Mirrors HarfBuzz’s unsafe_to_break flag.
