Struct FilterBoundary 

pub struct FilterBoundary {
    pub order: DrawOrder,
    pub bounds: Bounds<ScaledPixels>,
    pub content_mask: ContentMask<ScaledPixels>,
    pub corner_radii: Corners<ScaledPixels>,
    pub filters: SmallVec<[ScaledFilter; 4]>,
    pub opacity: f32,
    pub is_start: bool,
}

The start or end marker of a content-filter (filter) isolation group. The element’s subtree is painted between a matched start/end pair; the renderer redirects that span into an offscreen target, filters it, and composites it back at bounds. Produces the CSS filter effect (e.g. blurring the element and its children as a single group).

Fields

order: DrawOrder

bounds: Bounds<ScaledPixels>

content_mask: ContentMask<ScaledPixels>

corner_radii: Corners<ScaledPixels>

filters: SmallVec<[ScaledFilter; 4]>

The filter chain applied to the isolated group, in scene (device-pixel) space. Identity filters are dropped at paint time, so a FilterBoundary is only emitted when non-empty. Inline capacity 4 (same struct size as 1 here — see BackdropFilter::filters).

opacity: f32

is_start: bool

true for the start marker (opens the group), false for the end marker (closes it).
