Struct Upgrade 

pub struct Upgrade<'a, T: ?Sized> { /* private fields */ }

The future RwLockUpgradableReadGuard::upgrade returns. Dropping it before it completes releases the upgradable read.

Trait Implementations

impl<T: ?Sized> Debug for Upgrade<'_, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: ?Sized> Drop for Upgrade<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<'a, T: ?Sized> Future for Upgrade<'a, T>

type Output = RwLockWriteGuard<'a, T>

The type of value produced on completion.

fn poll( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<RwLockWriteGuard<'a, T>>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
