Trait AsyncUnlockable 

pub trait AsyncUnlockable {
    // Required method
    fn unlocked_async<'life0, 'async_trait, F, U>(
        s: &'life0 mut Self,
        f: F,
    ) -> Pin<Box<dyn Future<Output = U> + 'async_trait>>
       where F: AsyncFnOnce() -> U + 'async_trait,
             U: 'async_trait,
             Self: 'async_trait,
             'life0: 'async_trait;
}

A trait for lock guards that can be temporarily unlocked asynchronously. This is useful for performing async operations while holding a lock, without causing deadlocks or holding the lock for an extended period.

Required Methods

fn unlocked_async<'life0, 'async_trait, F, U>( s: &'life0 mut Self, f: F, ) -> Pin<Box<dyn Future<Output = U> + 'async_trait>>

where F: AsyncFnOnce() -> U + 'async_trait, U: 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Temporarily unlocks the guard s, executes the async function f, and then re-locks the guard. The lock is guaranteed to be re-acquired before this function returns.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
