Enum FramePass 

pub enum FramePass {
    Opening,
    Clear,
    Opaque,
    Surface,
    Page,
    Filter,
    Copy,
    Punch,
}

One render pass a frame recorded into the caller’s encoder — what EngineRenderer::last_frame_passes lists, in recording order.

The module doc’s The frame’s passes is the contract these name. The glyph-atlas replay’s passes are not among them: they are recorded on an encoder of the engine’s own, ahead of the frame (see crate::gpu::atlas).

Variants

Opening

The surface opening: clears the colour target (and the depth attachment, unless pre-cleared), then draws the opaque strips and the first surface round that draws, whichever of the two the frame has. The first pass over the surface whenever passes are merged.

Clear

The clear alone, drawing nothing — the first pass of a frame recorded with passes unmerged.

Opaque

The opaque strips alone, depth-writing, loading what the clear left — recorded only with passes unmerged.

Surface

A surface round’s blended strips, loading the surface.

Page

A layer page round, rendering into a pooled page.

Filter

One pass of a filter’s sequence, between two pooled pages.

Copy

A region copy: a region of the frame’s own target read back into a pooled page by one pass that clears the page and draws the region into it — preceded, on a target that can only be copied, by a transfer into the renderer’s staging texture (see RegionCopyMode) — ahead of a backdrop blur’s filter passes.

Punch

The destination-out hole punch, at a cut or after the last round.

Implementations

impl FramePass

pub const fn label(self) -> &'static str

The label the pass is recorded under, as a GPU capture shows it.

pub const fn targets_surface(self) -> bool

Whether the pass renders into the frame’s own target rather than into a pooled page.
