Struct FontScale 

Source 
pub struct FontScale(pub u16);
Expand description

Relative font-height multiplier, stored as hundredths (100 = 1.0×, 160 = 1.6×). Fixed-point rather than f32 so Style stays Eq + Hash (the theme is content-hashed into the cell-matrix version). An authoring StyleSpec carries an f32 ratio; resolution quantizes it here.

Implementations§

Source§

impl FontScale

Source

pub const ONE: FontScale

1.0× — the no-op scale.

Source

pub fn from_ratio(ratio: f32) -> FontScale

Quantize an f32 ratio (e.g. 1.6) to fixed-point hundredths. Clamps negatives to 0.

Source

pub fn as_ratio(self) -> f32

The multiplier as an f32 ratio (e.g. 1.6). Used by the GPUI peer when sizing a run.
