Trait concurrency_traits::rw_lock::AsyncUpgradeReadGuard

pub trait AsyncUpgradeReadGuard<'a>: Sized + TryUpgradeReadGuard<'a> {
    #[must_use]
    fn upgrade_async<'async_trait>(
        self
    ) -> Pin<Box<dyn Future<Output = Self::WriteGuard> + Send + 'async_trait>>
    where
        Self: 'async_trait;
}

A read guard that can be upgraded to a write guard asynchronously

Required methods

#[must_use]

fn upgrade_async<'async_trait>(
    self
) -> Pin<Box<dyn Future<Output = Self::WriteGuard> + Send + 'async_trait>> where
    Self: 'async_trait, 

Upgrades this guard asynchronously, returning a future that will contain the upgraded guard.
