pub enum GeneratorState<Y, R> {
Yielded(Y),
Complete(R),
}
generator_trait
)mtls
only.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)
generator_trait
)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)
generator_trait
)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.
