Instance properties

schemaread only typeof PACK_SCHEMA

The manifest’s schema, which a reader checks first (Rule 11.10).

compilerread only string

The package version that wrote it.

emitoptionalread only { readonly level?: 'O0' | 'O1' | 'O2'; readonly parens?: 'full' | 'minimal'; readonly fp64Flavor?: 'float' | 'integer'; }

The options the program was emitted under, when the build gave any of the three a manifest can record (packModule(m, { emit }), its plugins apart, which it cannot): the optimization level, the parens and the fp64Flavor. One the build did not give is absent and stands for its default ('O2', 'full' and 'float'), and a manifest built with none has no emit. The load-time emitter emits the program again under them (Rule 11.10).

wgslread only string

glsloptionalread only { readonly vertex: string; readonly fragment: string }

bindingsread only readonly PackBinding[]

vertexLayoutoptionalread only GpuVertexLayout

The first vertex entry’s vertex buffer, as entries[].vertex gives each.

entriesread only readonly PackEntry[]

structsread only readonly { readonly name: string; readonly fields: readonly { name: string; type: string }[]; }[]

overridesread only readonly PackOverride[]

featuresread only readonly string[]

The GPUFeatureNames a device must have to create the program’s pipelines.

consoleoptionalread only PackConsole

iroptionalread only PortableIr

The program as portable IR, when the build asked for it: what repack() emits again. Only the package version that wrote it reads it.

gloptionalread only { readonly draws: Readonly<Record<string, PackGlDraw | { readonly none: string }>>; }

What the WebGL2 tier uses: each full-screen fragment entry’s draw, or why it has none.
