Enum wasmtime_environ::__core::ops::GeneratorState

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

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

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)

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)

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.

Trait Implementations

impl<Y, R> Clone for GeneratorState<Y, R>where Y: Clone, R: Clone,

fn clone(&self) -> GeneratorState<Y, R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Y, R> Debug for GeneratorState<Y, R>where Y: Debug, R: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<Y, R> Hash for GeneratorState<Y, R>where Y: Hash, R: Hash,

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<Y, R> Ord for GeneratorState<Y, R>where Y: Ord, R: Ord,

fn cmp(&self, other: &GeneratorState<Y, R>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<Y, R> PartialEq<GeneratorState<Y, R>> for GeneratorState<Y, R>where Y: PartialEq<Y>, R: PartialEq<R>,

fn eq(&self, other: &GeneratorState<Y, R>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Y, R> PartialOrd<GeneratorState<Y, R>> for GeneratorState<Y, R>where Y: PartialOrd<Y>, R: PartialOrd<R>,

fn partial_cmp(&self, other: &GeneratorState<Y, R>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
