Enum deadpool::managed::HookError

pub enum HookError<E> {
    Continue(Option<HookErrorCause<E>>),
    Abort(HookErrorCause<E>),
}

Available on crate feature managed only.

Error structure which which can abort the creation and recycling of objects.

There are two variants HookError::Continue tells the pool to continue the running Pool operation (get, timeout_get or try_get) while HookError::Abort does abort that operation with an error.

Variants

Continue(Option<HookErrorCause<E>>)

This variant can be returned by hooks if the object should be discarded but the operation should be continued.

Abort(HookErrorCause<E>)

This variant causes the object to be discarded and aborts the operation.
