Struct AppBarMetrics 

pub struct AppBarMetrics {
    pub small_height: f64,
    pub collapsed_height: f64,
    pub medium_expanded: f64,
    pub large_expanded: f64,
    pub bottom_height: f64,
}

The resolved band heights of one density — upstream’s M3EAppBarMetrics, as produced by M3EAppBarTheme.metrics(density).

use frust_material::{AppBarDensity, AppBarMetrics, AppBarVariant};

let regular = AppBarMetrics::for_density(AppBarDensity::Regular);
assert_eq!(regular.small_height, 64.0);
assert_eq!(regular.expanded(AppBarVariant::Large), 152.0);

// Compact takes 8dp off every band but the bottom bar's.
let compact = AppBarMetrics::for_density(AppBarDensity::Compact);
assert_eq!(compact.small_height, 56.0);
assert_eq!(compact.bottom_height, regular.bottom_height);

Fields

small_height: f64

The fixed top bar’s band, in logical px.

collapsed_height: f64

The collapsing bar’s fully-collapsed band, in logical px.

medium_expanded: f64

The AppBarVariant::Medium expanded band, in logical px.

large_expanded: f64

The AppBarVariant::Large expanded band, in logical px.

bottom_height: f64

The bottom bar’s band, in logical px (density-independent).

Implementations

impl AppBarMetrics

pub const fn for_density(density: AppBarDensity) -> Self

The bands density resolves to.

pub const fn expanded(&self, variant: AppBarVariant) -> f64

The fully-expanded band of variant, in logical px — _buildSliver’s own switch (variant).
