Struct WorkspaceArena 

pub struct WorkspaceArena { /* private fields */ }

A handle to an Arena borrowed from the thread-local pool.

On drop, the arena is reset (all allocations invalidated) and returned to the pool. Because the pool is thread-local, this type is !Send.

Implementations

impl WorkspaceArena

pub fn acquire() -> Self

Acquire an arena from the thread-local pool, or create a fresh one if the pool is empty.

pub fn arena(&self) -> &Arena

Access the pooled arena.

pub fn reset(&mut self)

Reset the arena in place, invalidating all values allocated so far. References handed out before the reset must not be used afterwards.

Trait Implementations

impl Drop for WorkspaceArena

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.
