Enum BufferArg 

pub enum BufferArg<R: Runtime> {
    Handle {
        handle: BufferBinding<R>,
    },
    Alias {
        input_pos: usize,
        length: [usize; 1],
    },
}

Variants

Handle

The buffer is passed with a buffer handle.

Fields

handle: BufferBinding<R>

The buffer handle.

Alias

The buffer is aliasing another input buffer.

Fields

input_pos: usize

The position of the input buffer.

length: [usize; 1]

The length of the underlying handle

Implementations

impl<R: Runtime> BufferArg<R>

pub unsafe fn from_raw_parts(handle: Handle, length: usize) -> Self

Create a new buffer argument.

Safety

Specifying the wrong length may lead to out-of-bounds reads and writes.

pub unsafe fn from_raw_parts_binding( binding: BufferBinding, length: usize, ) -> Self

Create a new buffer argument from a binding.

Safety

Specifying the wrong length may lead to out-of-bounds reads and writes.

pub fn len(&self) -> usize

The buffer’s length in elements, as it was declared.

pub fn is_empty(&self) -> bool

Whether the buffer was declared empty.

pub fn alias(input_pos: usize, length: usize) -> Self

pub fn size(&self) -> usize

pub fn shape(&self) -> &[usize]
