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", so this trait is not object safe.
