Module scene_residency 

Scene residency bookkeeping: which scenes are pinned (their streamed content wanted on the GPU), which of each scene’s members are currently resident, and the derived per-scene load state and progress. Pure bookkeeping against core + alloc only, like the streaming policy core: the driver applies pin changes to the stream planners as blocked flags and reports residency transitions back here.

Structs

PinChanges

Pin changes produced by one sync_pins call, as planner blocked-flag updates the driver must apply.

SceneResidency

Per-scene residency pins, one refcount per resource and channel.

Enums

SceneLoadState

Load state of one scene’s streamed content, derived from pins + residency.

Constants

CHANNEL_MESH

Residency channel for meshes.

CHANNEL_SHADER

A shader bucket’s render pipeline, built on pin and released on unload. The item id is the bucket (the material’s ShaderHandle value).

CHANNEL_TEXTURE

Residency channel for textures.

Type Aliases

Member

A streamed item a scene exclusively owns: the driver’s channel tag (which pool the item lives in) plus the pool’s item id.
