Enum WaitOutcome 

#[non_exhaustive]
pub enum WaitOutcome<T> {
    Finished(T),
    TimedOut {
        last: Option<T>,
    },
    Vanished {
        last: T,
    },
}

The result of waiting. A finished state can still describe a failure, such as an action where some agents failed; inspect it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Finished(T)

TimedOut

The deadline passed. last is the most recent state observed, if any.

Fields

last: Option<T>

Vanished

The resource was observed and then could no longer be found, for example because it was deleted or fell outside the searched window. last is the final state observed.

Fields

last: T

Implementations

impl<T> WaitOutcome<T>

pub fn finished(self) -> Option<T>

Returns the state only for Self::Finished. This says that waiting ended, not that the operation succeeded. Use Self::last to inspect a state retained after a timeout or disappearance.

pub fn last(&self) -> Option<&T>

The most recent state observed, whatever the outcome.

Trait Implementations

impl<T: Clone> Clone for WaitOutcome<T>

fn clone(&self) -> Self

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for WaitOutcome<T>

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