Enum rustc_hir::CoroutineSource

pub enum CoroutineSource {
    Block,
    Closure,
    Fn,
}

In the case of a coroutine created as part of an async/gen construct, which kind of async/gen 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/gen block written by the user.

Closure

An explicit async/gen closure written by the user.

Fn

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

Trait Implementations

impl Clone for CoroutineSource

fn clone(&self) -> CoroutineSource

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CoroutineSource

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for CoroutineSource

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

impl Display for CoroutineSource

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

Formats the value using the given formatter.

impl<__E: SpanEncoder> Encodable<__E> for CoroutineSource

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

impl Hash for CoroutineSource

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 CoroutineSource

where __CTX: HashStableContext,

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

impl PartialEq for CoroutineSource

fn eq(&self, other: &CoroutineSource) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for CoroutineSource

impl Eq for CoroutineSource

impl StructuralPartialEq for CoroutineSource

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.
