Struct deadpool::managed::sync::SyncWrapper

source ·
pub struct SyncWrapper<T, E>
where T: Send + 'static, E: Send + 'static,
{ /* private fields */ }
👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.
Expand description

Wrapper for objects which only provides blocking functions that need to be called on a separate thread.

Access to the wrapped object is provided via the SyncWrapper::interact() method.

Implementations§

source§

impl<T, E> SyncWrapper<T, E>
where T: Send + 'static, E: Send + 'static,

source

pub async fn new<F>(runtime: Runtime, f: F) -> Result<Self, E>
where F: FnOnce() -> Result<T, E> + Send + 'static,

👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.

Creates a new wrapped object.

source

pub async fn interact<F, R>(&self, f: F) -> Result<R, InteractError<E>>
where F: FnOnce(&mut T) -> Result<R, E> + Send + 'static, R: Send + 'static,

👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.

Interacts with the underlying object.

Expects a closure that takes the object as its parameter. The closure is executed in a separate thread so that the async runtime is not blocked.

source

pub fn is_mutex_poisoned(&self) -> bool

👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.

Indicates whether the underlying Mutex has been poisoned.

This happens when a panic occurs while interacting with the object.

source

pub fn lock( &self, ) -> Result<SyncGuard<'_, T>, PoisonError<MutexGuard<'_, Option<T>>>>

👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.

Lock the underlying mutex and return a guard for the inner object.

source

pub fn try_lock( &self, ) -> Result<SyncGuard<'_, T>, TryLockError<MutexGuard<'_, Option<T>>>>

👎Deprecated since 0.9.1: This module has been deprecated in favor of the dedicated deadpool-sync utility crate.

Try to lock the underlying mutex and return a guard for the inner object.
