Enum KernelArg 

pub enum KernelArg<'a> {
    Buffer(DevicePtr),
    Bytes(&'a [u8]),
}

2026-09-25: A typed kernel argument for launch_typed. The Metal backend binds buffers with setBuffer:offset:atIndex: and bytes with setBytes:length:atIndex:; CUDA packs both into parameter slots.

Variants

Buffer(DevicePtr)

2026-09-25: A device address. The Metal backend resolves it to its owning MTLBuffer and offset; CUDA passes the u64 as is.

Bytes(&'a [u8])

2026-09-25: Scalar or struct bytes, passed by value. CUDA packs them into 8-byte slots, zero-padding the last (pack_kernel_args).
