Struct AsyncFixedArena 

pub struct AsyncFixedArena<W = NotifyWaiters> { /* private fields */ }

Async-capable wrapper around FixedArena.

Created via FixedArenaBuilder::build_async(). allocate_async() parks until a slot becomes available. Sync methods remain accessible through Deref<Target = FixedArena>.

Implementations

impl<W: Waiter> AsyncFixedArena<W>

pub async fn allocate_async(&self) -> Buffer

Allocate a buffer, waiting asynchronously if the arena is full.

Returns once a slot becomes available. The bitmap is the source of truth; notifications are hints to retry.

Methods from Deref<Target = FixedArena>

pub fn slot_count(&self) -> usize

Number of slots in this arena.

pub fn slot_capacity(&self) -> usize

Capacity of each slot in bytes (aligned).

pub fn metrics(&self) -> FixedArenaMetrics

Snapshot current allocator metrics.

pub fn allocate(&self) -> Result<Buffer, AllocError>

Allocate a buffer. Returns Err(AllocError::ArenaFull) if all slots are in use.

Trait Implementations

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

Performs copy-assignment from source.

impl<W> Debug for AsyncFixedArena<W>

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

Formats the value using the given formatter.

impl<W> Deref for AsyncFixedArena<W>

type Target = FixedArena

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
