Trait MutexLike 

pub trait MutexLike<T: Send + 'static>: Send + Sync {
    type Guard<'guard>: DerefMut<Target = T> + Send
       where Self: 'guard;

    // Required method
    fn lock(&self) -> impl Future<Output = Self::Guard<'_>> + Send;
}

Async mutex shape. The guard type is borrowed so callers can hold the lock across an await without paying a clone. Implementations supply the actual lock primitive — tokio::sync::Mutex<T> for the tokio impl, a per-core single-writer lock for prime.

Required Associated Types

type Guard<'guard>: DerefMut<Target = T> + Send where Self: 'guard

Required Methods

fn lock(&self) -> impl Future<Output = Self::Guard<'_>> + Send

Acquire the lock. The returned future resolves when the guard is available; the guard holds the lock until dropped.

Dyn Compatibility

This trait is not dyn compatible.

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