Enum tracing_core::stdlib::ops::CoroutineState

source ยท
pub enum CoroutineState<Y, R> {
    Yielded(Y),
    Complete(R),
}
๐Ÿ”ฌThis is a nightly-only experimental API. (coroutine_trait #43122)
Expand description

The result of a coroutine resumption.

This enum is returned from the Coroutine::resume method and indicates the possible return values of a coroutine. Currently this corresponds to either a suspension point (Yielded) or a termination point (Complete).

Variantsยง

ยง

Yielded(Y)

๐Ÿ”ฌThis is a nightly-only experimental API. (coroutine_trait #43122)

The coroutine suspended with a value.

This state indicates that a coroutine has been suspended, and typically corresponds to a yield statement. The value provided in this variant corresponds to the expression passed to yield and allows coroutines to provide a value each time they yield.

ยง

Complete(R)

๐Ÿ”ฌThis is a nightly-only experimental API. (coroutine_trait #43122)

The coroutine completed with a return value.

This state indicates that a coroutine has finished execution with the provided value. Once a coroutine has returned Complete it is considered a programmer error to call resume again.
