Struct PooledBuffer 

pub struct PooledBuffer { /* private fields */ }

A buffer borrowed from a pool that automatically returns on drop.

Provides RAII semantics - the buffer is automatically returned to the pool when dropped, ensuring no buffer leaks even in error conditions.

Safety

Maintains all safety guarantees of PinnedBuffer while adding automatic pool return semantics.

Implementations

impl PooledBuffer

pub fn buffer(&self) -> &PinnedBuffer<[u8]>

Get a reference to the underlying buffer.

Panics

Panics if the buffer has already been returned (internal bug).

pub fn buffer_mut(&mut self) -> &mut PinnedBuffer<[u8]>

Get a mutable reference to the underlying buffer.

Panics

Panics if the buffer has already been returned (internal bug).

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

Get a pinned mutable slice reference to the buffer data.

This maintains pinning guarantees required for io_uring operations.

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

Get an immutable slice reference to the buffer data.

pub fn len(&self) -> usize

Get the length of the buffer.

pub fn is_empty(&self) -> bool

Check if the buffer is empty.

pub fn detach(self) -> PinnedBuffer<[u8]>

Detach the buffer from the pool, taking ownership.

This removes the buffer from pool management, preventing automatic return on drop. Use when you need to transfer ownership elsewhere.

Trait Implementations

impl Debug for PooledBuffer

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

Formats the value using the given formatter.

impl Drop for PooledBuffer

fn drop(&mut self)

Automatically return the buffer to the pool when dropped.

Ensures proper resource management even in error conditions.
