Struct Buffer

pub struct Buffer<K: BufferLayout> {
    pub buffer: Buffer,
    pub count: usize,
    pub len: usize,
    pub max: usize,
    /* private fields */
}

GPU Buffer Management Struct. Used to keep track of Counts, Length and The Buffer in the GPU.

Fields

buffer: Buffer

count: usize

len: usize

max: usize

Implementations

impl<K: BufferLayout> Buffer<K>

pub fn new( gpu_device: &GpuDevice, contents: &[u8], usage: BufferUsages, label: Option<&str>, ) -> Self

Used to create a Buffer.

Arguments

• contents: The contents to Create the Buffer with.
• usage: wgpu usage flags wgpu::BufferUsages
• label: Label to be seen in GPU debugging.

pub fn write(&self, device: &GpuDevice, data: &[u8], pos: u64)

Writes Data into the Buffer from its Position.

Panics

• This method fails if data overruns the size of buffer starting at pos.

Arguments

• data: the contents to write to the Buffer.
• pos: Position to write to the buffer from.

pub fn is_empty(&self) -> bool

If the buffer len is empty.

pub fn buffer_slice(&self, range: Range<u64>) -> BufferSlice<'_>

Returns a wgpu::BufferSlice of the buffer to hand off to the GPU.
