Struct PoolAllocation 

pub struct PoolAllocation<'p> { /* private fields */ }

A region of memory carved from a pool. Drops decrement the pool’s live count.

Implementations

impl<'p> PoolAllocation<'p>

pub fn len(&self) -> usize

Byte length of this region.

pub fn is_empty(&self) -> bool

True if zero-length (never for a successfully created allocation).

pub fn offset(&self) -> usize

Offset within the underlying slab.

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

Borrow as a shared byte slice.

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

Borrow as a mutable byte slice.

&mut self and the disjoint-region invariant of bump allocation together prove no other live alias points at [offset, offset+size).

Trait Implementations

impl Debug for PoolAllocation<'_>

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

Formats the value using the given formatter.

impl Drop for PoolAllocation<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
