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

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

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

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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
