class Capabilities

설명

Membership in the profile’s keys is support, so the set and the profile are one fact.

The capability gate that runs before every emit uses it: it derives what a module needs (a storage binding needs storageBuffer, a @compute entry needs compute, a multisampled texture load needs msaaTextureLoad, plus whatever the module lists in enables), calls covers(reqs), and on a miss calls missing(reqs) to name the capabilities the target cannot emit. The thrown UnsupportedFeatureError then reads “backend ‘glsl-es300’ cannot emit this module: missing capabilities: compute”, with the whole module as context. This is why the GLSL ES 3.00 capProfile has no row for storageBuffer, compute, or msaaTextureLoad: the gate refuses the module before the writer sees it.

fromProfile (profile: CapProfile): Capabilities

The capabilities a capProfile declares, read from its keys. Build coverage this way so that profile membership and capability coverage stay one fact.

has (c: Capability): boolean

covers (reqs: Iterable<Capability>): boolean

True iff this target supports everything reqs needs.
