index
The index in the argument table that corresponds to the function argument.
Declaration
var index: Int { get }Discussion
A command encoder (MTLComputeCommandEncoder or MTLRenderCommandEncoder) specifies the index in the corresponding argument table. For example, an app can call the setTexture(_:index:) method of MTLComputeCommandEncoder to specify an index in the texture argument table for an MTLTexture instance that is used as an argument of a compute function.
