`CapSupport`

Interface in Backends

What one capability costs on one target: the row of a backend's capProfile.

import type { CapSupport } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

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

Description

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).

Instance properties

directiveoptionalread only 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.
hostFeatureoptionalread only 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.
