Struct Buffer 

pub struct Buffer<T: Pod> { /* private fields */ }

A typed GPU buffer.

Buffer<T> owns a region of GPU memory containing len elements of type T. Data is moved to the GPU on creation (Device::upload) and read back on demand (Buffer::download).

Implementations

impl<T: Pod> Buffer<T>

pub const fn len(&self) -> usize

Number of T elements in this buffer.

pub const fn is_empty(&self) -> bool

Whether the buffer is empty.

pub const fn byte_size(&self) -> u64

Size in bytes.

pub fn download(&self) -> Result<Vec<T>>

Copy buffer contents back to the CPU.

This blocks until the transfer is complete.
