Module Metal.Device

Represents the GPU device capable of executing Metal commands. See MTLDevice.

type t
val sexp_of_t : t -> Sexplib0.Sexp.t
val create_system_default : unit -> t

Returns the default Metal device for the system. See MTLCreateSystemDefaultDevice.

val copy_all_devices : unit -> t array

Returns an array of all the Metal device instances in the system. See MTLCopyAllDevices.

module GPUFamily : sig ... end

Represents a Metal GPU family, categorizing devices by feature set and capability. See MTLGPUFamily.

val supports_family : t -> GPUFamily.t -> bool

Checks if the device supports the specified GPU family. See supportsFamiliy:.

module ArgumentBuffersTier : sig ... end

Describes the level of support for argument buffers. See MTLArgumentBuffersTier.
