Struct IsolatedBudgetConfig

pub struct IsolatedBudgetConfig {
    pub max_offscreen_surface_px: u64,
    pub max_offscreen_bytes_per_frame: u64,
    pub max_blur_radius_px: f32,
    pub max_isolated_passes_per_frame: u32,
    pub max_isolated_nesting_depth: u8,
    pub max_backdrop_captures_per_frame: u32,
    pub max_backdrop_blur_radius_px: f32,
    pub max_blend_captures_per_frame: u32,
}

Per-frame offscreen budgets (defaults suitable for 1080p-class UIs).

Byte estimates assume four bytes per color pixel and another four bytes per pixel when stencil is required. Limits are independent: satisfying one does not bypass the pass-count, depth, or capture limits.

Examples

use ailloli_ui_render_wgpu::IsolatedBudgetConfig;
let config = IsolatedBudgetConfig::default();
assert_eq!(config.max_isolated_passes_per_frame, 8);
assert_eq!(config.max_offscreen_surface_px, 1920 * 1080);

Fields

max_offscreen_surface_px: u64

Maximum width * height for one isolated surface (physical pixels).

max_offscreen_bytes_per_frame: u64

Maximum estimated bytes for all offscreen slots in one frame.

max_blur_radius_px: f32

Largest content-blur radius, in physical pixels.

max_isolated_passes_per_frame: u32

Maximum number of isolated passes scheduled in one frame.

max_isolated_nesting_depth: u8

Maximum isolated nesting depth (0 = root only). nested isolated compositor.

max_backdrop_captures_per_frame: u32

Max backdrop snapshots per frame (backdrop filter).

max_backdrop_blur_radius_px: f32

Largest backdrop-blur radius, in physical pixels.

max_blend_captures_per_frame: u32

Max dst captures for shader blend compositing per frame (blend modes).

Trait Implementations

impl Clone for IsolatedBudgetConfig

fn clone(&self) -> IsolatedBudgetConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IsolatedBudgetConfig

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

Formats the value using the given formatter.

impl Default for IsolatedBudgetConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for IsolatedBudgetConfig

fn eq(&self, other: &IsolatedBudgetConfig) -> 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.
