Struct BufferPoolKey 

pub struct BufferPoolKey {
    pub device: DeviceSpec,
    pub dtype: DType,
    pub size: usize,
}

Key for buffer pooling - groups buffers that can be reused interchangeably.

Buffer reuse is shape-agnostic: codegen reads logical shape from the UOp graph, runtime dispatch passes raw *mut u8 pointers, and the planner skips output buffers (the only consumers of Buffer::shape() via as_array/as_array_mut). Two non-output buffers with the same (device, dtype, rounded_size) are interchangeable storage regardless of their logical shapes.

Fields

device: DeviceSpec

Device where buffer is allocated.

dtype: DType

Data type of buffer elements.

size: usize

Buffer size in bytes (rounded up to MIN_BLOCK_SIZE).

Trait Implementations

impl Clone for BufferPoolKey

fn clone(&self) -> BufferPoolKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BufferPoolKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for BufferPoolKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BufferPoolKey

fn eq(&self, other: &BufferPoolKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
