Enum LineHeightSpec 

pub enum LineHeightSpec {
    Multiplier(f32),
    Px(f32),
}

Resolved CSS line-height: either a multiplier of the element’s font size (unitless, e.g. line-height: 1.5) or an absolute value in logical pixels (line-height: 24px).

Mirrors lumen_ir::layout_ir::LineHeightSpec field-for-field; duplicated here because lumen-core cannot depend on lumen-ir (lumen-ir already depends on lumen-core, so the reverse edge would cycle). The runtime converts between the two 1:1 at the IR/ECS boundary (spawn, restyle).

Variants

Multiplier(f32)

Multiple of the resolved font size.

Px(f32)

Absolute value in logical pixels.

Implementations

impl LineHeightSpec

pub fn resolve(self, size_px: f32) -> f32

Resolve against a font size in logical pixels.

Trait Implementations

impl Clone for LineHeightSpec

fn clone(&self) -> LineHeightSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineHeightSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LineHeightSpec

fn eq(&self, other: &LineHeightSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
