# Enum std::ops::GeneratorState

source ·

    pub enum GeneratorState<Y, R> {
        Yielded(Y),
        Complete(R),
    }

🔬This is a nightly-only experimental API. (`generator_trait` #43122)
Expand description

The result of a generator resumption.

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

## Variants§

§

### Yielded(Y)

🔬This is a nightly-only experimental API. (`generator_trait` #43122)

The generator suspended with a value.

This state indicates that a generator 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 generators to provide a value each time they yield.

§

### Complete(R)

🔬This is a nightly-only experimental API. (`generator_trait` #43122)

The generator completed with a return value.

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