Struct Buffer 

pub struct Buffer {
    pub length: usize,
    pub usage: BufferUsages,
    pub buffer: Buffer,
}

A wrapper around wgpu::Buffer that can be updated in place.

Fields

length: usize

Current length of the backing storage in bytes

usage: BufferUsages

Parameter of Buffer::new

buffer: Buffer

Allocated backing storage

Implementations

impl Buffer

pub fn new(device: &Device, usage: BufferUsages, data: &[u8]) -> Self

Creates a new Buffer

Note: usage must include wgpu::BufferUsages::COPY_DST so that Buffer::update can be used.

pub fn update(&mut self, device: &Device, queue: &Queue, data: &[u8])

Updates an existing buffer in place if possible or reallocates it

pub fn get_binding<R: RangeBounds<u64>>(&self, range: R) -> BufferBinding<'_>

Returns a wgpu::BufferBinding for a slice of this buffer
