Struct PooledBuffer 

pub struct PooledBuffer { /* private fields */ }

An owned, pool-tracked byte buffer.

Created exclusively by TensorPool::acquire and must be returned to the same pool via TensorPool::release. There is no Drop guard — callers are responsible for calling release. This is an intentional design choice to avoid the need for Arc<TensorPool> references inside the buffer struct and to keep zero-copy paths maximally thin.

Implementations

impl PooledBuffer

pub fn bucket(&self) -> usize

Returns the bucket index this buffer is classified under.

pub fn as_slice(&self) -> &[u8]

Immutable view of the buffer contents.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Mutable view of the buffer contents.

pub fn capacity(&self) -> usize

The total pre-allocated capacity of the underlying Vec<u8>.

pub fn len(&self) -> usize

The current logical length (number of initialized bytes).

pub fn is_empty(&self) -> bool

Returns true if len() == 0.

pub fn resize(&mut self, new_len: usize, val: u8)

Resize the buffer, filling any new bytes with val.

Delegates directly to Vec::resize.

pub fn into_inner(self) -> Vec<u8>

Consume the PooledBuffer and return the raw inner Vec<u8>.

The caller takes ownership; the buffer is not returned to the pool. Prefer TensorPool::release to reuse buffers.
