Interface: ResourceLifetime ​

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:12

Per-resource analysis result. The transient pool consumes these to decide aliasing (same bucket key, disjoint [firstUseIdx, lastUseIdx] intervals can share a physical wrapper) and final allocation.

Properties ​

name ​

name: string

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:13

kind ​

kind: TransientResourceKind

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:14

desc ​

desc: TextureDesc | BufferDesc

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:17

Original desc as passed to b.declareTexture / b.declareBuffer. The analyzer never mutates it.

firstUseIdx ​

firstUseIdx: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:22

Index into the topo-sorted pass order at which this resource is first written or read. Number.POSITIVE_INFINITY if no enabled pass references it — the analyzer emits a console.warn for these "orphan" declarations.

lastUseIdx ​

lastUseIdx: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:25

Last index at which this resource is referenced. -1 if no enabled pass references it.

resolvedUsage ​

resolvedUsage: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:29

Final unioned GPUTextureUsage / GPUBufferUsage bitmask after combining the desc's usage field with every access hint contribution recorded in TransientResourceRegistry.

resolvedWidth? ​

optional resolvedWidth?: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:31

Resolved pixel width (textures only). Undefined for buffers.

resolvedHeight? ​

optional resolvedHeight?: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:33

Resolved pixel height (textures only). Undefined for buffers.

resolvedSize? ​

optional resolvedSize?: number

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:35

Resolved byte size (buffers only). Undefined for textures.

persistent ​

persistent: boolean

Defined in: src/gfx/renderJob/graph/transient/LifetimeAnalyzer.ts:39

True ⇒ this resource is externally owned (imported) or explicitly marked aliasable: false. The pool MUST NOT alias it with any other lifetime in the same bucket.
