Module execute 

Rendering a recording, pass by pass.

Here rather than in the crate that wraps a backend, because a recording is defined here and executing one is nothing more than reading it: a layer is a target allocated at that pass’s size, rendered into, and sampled by a later pass. Nothing about that is backend-specific, so it is written once and generic over the HAL. It had been private to the public crate, which left the test harness with the choice of duplicating it or staying at the batch level where layers cannot be expressed.

Structs

Transient

The textures a recording needs that it did not arrive with.

Functions

execute

Render every pass of a recording, layers first, root into the surface.

execute_deferred

Render a recording’s layers, then submit its root without waiting.

execute_layers

Render every pass except the root, returning the layer targets in order.

render_offscreen

Render a recording into a texture this function allocates, and read it back.

render_offscreen_into

The same, into a target of the caller’s choosing.

resolve_sources

Resolve one pass’s slot table against the caller’s images and the layers rendered so far.
