Allows dispatching a function call to all its enum value implementations. See BackendDeviceType in usb/backend/device.rs for an example usage of it.

Arguments

• self - Replacement for the local self reference in the function call.
• enum - Enum name that the macro is matching on.
• types - Space-separated list of value types of the given enum.
• func - Function name that will be called by each match arm.
• param - Optional parameters needed for the given function call.
