# Enum std::ops::GeneratorState [−][src]

#[lang = "generator_state"]pub enum GeneratorState<Y, R> { Yielded(Y), Complete(R), }

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)`

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)`

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.
