Struct mimicry::AnswersGuard

pub struct AnswersGuard<'a, V> { /* private fields */ }

Guard ensuring that answers sent from an AnswersSender are timely consumed.

The consumption check is performed on guard drop: either implicit, or explicit via Self::scope().

Implementations

impl<V> AnswersGuard<'_, V>

pub fn scope<R>(self, action: impl FnOnce() -> R) -> R

Executes the provided closure and checks that all the answers were consumed by it.

pub async fn async_scope<Fut: Future>(self, action: Fut) -> Fut::Output

Executes the provided future and checks that all the answers were consumed by it.

While Self::scope().await with a closure that returns a future technically works, it will probably result in a failed consumption check. Indeed, the scope will be exited and the guard dropped before the future is polled.

pub fn discard(self)

Drops this guard discarding any remaining answers, so that the guard does not panic.
