Struct FixedMeasure 

pub struct FixedMeasure {
    pub sizes: HashMap<String, (f32, f32)>,
    pub wrap: bool,
}

The geometry-test measure every platform reproduces exactly: 8 px per character on ONE 20 px line (no wrapping), fixed boxes per control, or an explicit size per node id (fixtures/layout-geometry.json measures).

Fields

sizes: HashMap<String, (f32, f32)>

wrap: bool

When true, text leaves WRAP at 8 px per character (for the list and overlay tests); the geometry fixture keeps it off.

Implementations

impl FixedMeasure

pub fn with_sizes(sizes: HashMap<String, (f32, f32)>) -> FixedMeasure

pub fn intrinsic(&self, leaf: &LeafRequest<'_>) -> (f32, f32)

The intrinsic size of a leaf by kind (the spike’s table).

pub fn baseline(&self, leaf: &LeafRequest<'_>, height: f32) -> Option<f32>

The fixed baseline: the first 20 px line’s ascent, centred in a control’s box; none for boxes without text.

Trait Implementations

impl Clone for FixedMeasure

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FixedMeasure

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

Formats the value using the given formatter.

impl Default for FixedMeasure

fn default() -> Self

Returns the “default value” for a type.

impl Measure for FixedMeasure

fn measure_id(&self) -> u64

Identity of this measurer (font scale, Dynamic Type state…). Two consecutive passes with different ids invalidate every memo.

fn measure_intrinsics(&mut self, leaves: &[LeafRequest<'_>]) -> Vec<Intrinsics>

fn measure_heights( &mut self, leaves: &[LeafRequest<'_>], requests: &[HeightRequest], ) -> Vec<f32>
