interface CapSupport {
  readonly directive?: string;
  readonly hostFeature?: string;
}

설명

What one capability costs on one target: the row of a backend’s capProfile. Both fields are optional and mean different things.

An empty row ({}) means the target supports the capability outright, with no directive and no host activation (storage buffers on WGSL, float render targets on WebGPU).

인스턴스 속성

directive선택 사항읽기 전용 string: The token the emitted source must carry for this target to accept the feature: WGSL enable <directive>;, GLSL ES 3.00 #extension <directive> : require. When absent, the feature adds nothing to the emitted source.
hostFeature선택 사항읽기 전용 string: What the host must activate before pipeline creation: gl.getExtension('<hostFeature>') on WebGL2, a requiredFeatures: ['<hostFeature>'] entry on WebGPU. When absent, the feature is core on that target and there is nothing to request.
