Enum WidthSource 

pub enum WidthSource {
    Metric,
    Estimate,
}

Whether a text span’s width was computed from real font metrics or estimated.

Variants

Metric

Width derived from the font’s actual glyph advance (hmtx, CFF, Type1 charstring).

Estimate

Width estimated at 50 % of font size — no glyph metric was available.

Implementations

impl WidthSource

pub fn as_str(&self) -> &'static str

Stable label used across SDK bindings and the JSON wire form ("Metric" / "Estimate"). Single source of truth for the string; the serde derive on the enum produces identical values.
