Struct BlurRequest 

pub struct BlurRequest {
    pub source_region: Region,
    pub target_rect: Region,
    pub strength: BlurStrength,
    pub tint: Tint,
    pub corner_radius: CornerRadius,
    pub opacity: Opacity,
}

The one backend-agnostic bundle that crosses the seam. source_region says where the backdrop lives in the source texture; target_rect says where to composite the frosted surface in the target. Both carry independent sizes and scales (DESIGN §4.1/§4.3).

Fields

source_region: Region

Where the backdrop to blur lives in the source texture (physical px + its scale).

target_rect: Region

Where to composite the frosted surface in the target (physical px + its scale).

strength: BlurStrength

How much blur (logical points).

tint: Tint

The glass film.

corner_radius: CornerRadius

How round the surface corners are (logical points).

opacity: Opacity

Surface-global fade coverage [0, 1] — how present the whole surface is (default 1.0).

Implementations

impl BlurRequest

pub fn physical_blur_radius(&self) -> f32

The physical-pixel blur radius, resolved against the source region’s scale.

The blur convolution happens in source-texture pixel space, so this is the only correct scale; pinning it here (rather than exposing a bare strength.to_physical_radius(scale)) means a backend cannot accidentally resolve against target_rect.scale on a mismatched-DPI surface. Mirrors how ResolvedMask::from_target pins the target scale for the corner radius.

Trait Implementations

impl Clone for BlurRequest

fn clone(&self) -> BlurRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BlurRequest

impl Debug for BlurRequest

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

Formats the value using the given formatter.

impl PartialEq for BlurRequest

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