Struct FontWidth 

pub struct FontWidth(pub f32);

The requested width of a font face, as a percentage of its normal width.

100.0 is FontWidth::NORMAL. Smaller values select condensed faces, and larger values select expanded faces. Use the named constants for standard steps, or any value in between. Font carries this value into text shaping. For a variable font, the backend uses it for the wdth axis and clamps it to that axis’s range.

Examples

let narrow = Font {
    width: FontWidth::CONDENSED,
    ..font("Noto Sans")
};
assert_eq!(narrow.width, FontWidth(75.0));
