Trait concurrency_traits::AsyncRwLockSized[−][src]

pub trait AsyncRwLockSized<'a>: Sized + AsyncRwLock<'a> + TryRwLockSized<'a> {
    fn read_async_func<F>(
        &'a self, 
        func: impl FnOnce(&Self::Item) -> F + 'a
    ) -> Pin<Box<dyn Future<Output = F::Output> + 'a>>
    where
        F: Future,
    { ... }

    fn write_async_func<F>(
        &'a self, 
        func: impl FnOnce(&mut Self::Item) -> F + 'a
    ) -> Pin<Box<dyn Future<Output = F::Output> + 'a>>
    where
        F: Future,
    { ... }
}

The functions for AsyncRwLock that only work for sized types. Separated to allow AsyncRwLock to be a trait object.

Provided methods

fn read_async_func<F>(
    &'a self,
    func: impl FnOnce(&Self::Item) -> F + 'a
) -> Pin<Box<dyn Future<Output = F::Output> + 'a>> where
    F: Future, [src]

Reads from the lock and runs func on the result asynchronously

Implementation

Should be overwritten by implementors if can be more optimal than creating a guard

fn write_async_func<F>(
    &'a self,
    func: impl FnOnce(&mut Self::Item) -> F + 'a
) -> Pin<Box<dyn Future<Output = F::Output> + 'a>> where
    F: Future, [src]

Writes to the lock and runs func on the result asynchronously

Implementation

Should be overwritten by implementors if can be more optimal than creating a guard
