Struct PooledInstance 

pub struct PooledInstance<T, E>
where
    T: Send + 'static,
    E: PoolResourceLimit + Send + Sync + 'static,
{ /* private fields */ }

RAII wrapper acquired from an InstancePool: holds the instance and returns it to the pool on drop.

Adapters use this to make “acquire-call-release” exception-safe — if the plugin call panics, the instance still returns home (drop runs).

Implementations

impl<T, E> PooledInstance<T, E>

where T: Send + 'static, E: PoolResourceLimit + Send + Sync + 'static,

pub fn acquire(pool: Arc<InstancePool<T, E>>) -> Result<Self, E>

Acquire a fresh PooledInstance from the pool.

Errors

Propagates InstancePool::acquire.

pub fn get_mut(&mut self) -> &mut T

Mutable access to the instance.

Panics

If called after Self::take.

pub fn take(self) -> T

Consume the wrapper, returning the inner instance and not releasing it to the pool. Use this if the instance is known to be corrupted (e.g., trapped on epoch interrupt).

Trait Implementations

impl<T, E> Debug for PooledInstance<T, E>

where T: Send + 'static, E: PoolResourceLimit + Send + Sync + 'static,

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

Formats the value using the given formatter.

impl<T, E> Drop for PooledInstance<T, E>

where T: Send + 'static, E: PoolResourceLimit + Send + Sync + 'static,

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.
