    Type Alias ShaderOverrideDef<T>Advanced

    ShaderOverrideDef:
        | { default: number; required?: never; type: T }
        | { default?: never; required: true; type: T }

    A specialization constant a bit declares: a default, or required: true

    The value comes from ShaderDescriptorOptions#overrides. Bits that declare the same constant must agree on its type, whether it's required, and its default, or the compile throws.
