Type Alias BufferDescriptor 

pub type BufferDescriptor<'a> = BufferDescriptor<Option<&'a str>>;

Available on crate feature unstable-wgpu-27 only.

Describes a Buffer.

For use with Device::create_buffer.

Corresponds to WebGPU GPUBufferDescriptor.

Aliased Type

#[repr(C)]
pub struct BufferDescriptor<'a> {
    pub label: Option<&'a str>,
    pub size: u64,
    pub usage: BufferUsages,
    pub mapped_at_creation: bool,
}

Fields

label: Option<&'a str>

Debug label of a buffer. This will show up in graphics debuggers for easy identification.

size: u64

Size of a buffer, in bytes.

usage: BufferUsages

Usages of a buffer. If the buffer is used in any way that isn’t specified here, the operation will panic.

Specifying only usages the application will actually perform may increase performance. Additionally, on the WebGL backend, there are restrictions on BufferUsages::INDEX; see DownlevelFlags::UNRESTRICTED_INDEX_BUFFER for more information.

mapped_at_creation: bool

Allows a buffer to be mapped immediately after they are made. It does not have to be BufferUsages::MAP_READ or BufferUsages::MAP_WRITE, all buffers are allowed to be mapped at creation.

If this is true, size must be a multiple of COPY_BUFFER_ALIGNMENT.
