Struct SnapshotFrame 

pub struct SnapshotFrame {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<u8>,
    pub geometry: Vec<SnapshotIconGeometry>,
}

Off-screen render output from DesktopBackend::render_overlay_snapshot.

Pixel buffer is tightly-packed premultiplied BGRA — stride = width * 4 (no row padding). Callers can hand it directly to any image library that accepts BGRA with a known stride (e.g. PIL’s Image.frombuffer("RGBA", (w, h), buf, "raw", "BGRA", 0, 1)).

geometry is the authoritative per-icon paint answer, populated from D2D’s per-icon DrawBitmap rect and DirectWrite’s IDWriteTextLayout::GetMetrics. Callers doing pixel-level diagnostics should prefer these rects to any CV-based segmentation of pixels. Backends that can’t compute geometry (e.g. the platform stub) return an empty geometry vector.

Fields

width: u32

height: u32

pixels: Vec<u8>

Row-major premultiplied BGRA pixel data.

geometry: Vec<SnapshotIconGeometry>

One entry per icon that was actually drawn into the frame, in the same order as the caller’s positions slice. Skips icons whose id was not present in the backend’s cache.

Trait Implementations

impl Clone for SnapshotFrame

fn clone(&self) -> SnapshotFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotFrame

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

Formats the value using the given formatter.

impl Eq for SnapshotFrame

impl PartialEq for SnapshotFrame

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