Enum rustc_hir::AsyncGeneratorKind

pub enum AsyncGeneratorKind {
    Block,
    Closure,
    Fn,
}

In the case of a generator created as part of an async construct, which kind of async construct caused it to be created?

This helps error messages but is also used to drive coercions in type-checking (see #60424).

Variants

Block

An explicit async block written by the user.

Closure

An explicit async closure written by the user.

Fn

The async block generated as the body of an async function.

Implementations

impl AsyncGeneratorKind

pub fn descr(&self) -> &'static str

Trait Implementations

impl Clone for AsyncGeneratorKind

fn clone(&self) -> AsyncGeneratorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AsyncGeneratorKind

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for AsyncGeneratorKind

fn decode(__decoder: &mut __D) -> Self

impl Display for AsyncGeneratorKind

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

Formats the value using the given formatter.

impl<__E: Encoder> Encodable<__E> for AsyncGeneratorKind

fn encode(&self, __encoder: &mut __E)

impl Hash for AsyncGeneratorKind

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

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<__CTX> HashStable<__CTX> for AsyncGeneratorKindwhere __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq<AsyncGeneratorKind> for AsyncGeneratorKind

fn eq(&self, other: &AsyncGeneratorKind) -> 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
