Struct DeviceBuffer 

pub struct DeviceBuffer {
    pub data: Vec<f32>,
    pub size: usize,
    pub device_id: usize,
}

Device memory buffer (opaque handle).

For CPU and stub backends this is simply a heap-allocated Vec<f32>. A future hardware backend would replace data with a raw device pointer and keep the Vec only as a host-side staging buffer.

Fields

data: Vec<f32>

CPU backing store (used by all stub backends).

size: usize

Number of f32 elements in the buffer.

device_id: usize

Logical device index this buffer is associated with.

Implementations

impl DeviceBuffer

pub fn new(size: usize, device_id: usize) -> Self

Allocate a zero-initialised buffer of size elements on device_id.

pub fn from_slice(data: &[f32], device_id: usize) -> Self

Create a buffer pre-populated from a host slice.

pub fn to_vec(&self) -> Vec<f32>

Copy the buffer contents back to a host Vec<f32>.

pub fn size(&self) -> usize

Number of f32 elements stored in this buffer.

pub fn device_id(&self) -> usize

Logical device index this buffer is bound to.
