Struct DeviceBuffer 

pub struct DeviceBuffer {
    pub data: Vec<u8>,
    pub count: usize,
    pub element_type: ElementType,
}

CPU-side buffer representing device memory.

Fields

data: Vec<u8>

Raw bytes of the buffer.

count: usize

Number of elements in the buffer.

element_type: ElementType

Element data type.

Implementations

impl DeviceBuffer

pub fn from_f32(data: &[f32]) -> DeviceBuffer

Create a buffer from an f32 slice.

pub fn zeros_f32(count: usize) -> DeviceBuffer

Create a zero-filled f32 buffer.

pub fn from_u32(data: &[u32]) -> DeviceBuffer

Create a buffer from a u32 slice.

pub fn zeros_u32(count: usize) -> DeviceBuffer

Create a zero-filled u32 buffer.

pub fn from_i32(data: &[i32]) -> DeviceBuffer

Create a buffer from an i32 slice.

pub fn to_f32(&self) -> Result<Vec<f32>, RuntimeError>

Read buffer contents as f32 values.

Errors

Returns RuntimeError::Memory if the buffer element type is not f32.

pub fn to_u32(&self) -> Result<Vec<u32>, RuntimeError>

Read buffer contents as u32 values.

Errors

Returns RuntimeError::Memory if the buffer element type is not u32.

pub fn size_bytes(&self) -> usize

Total size of the buffer in bytes.
