Enum CoroutineKind 

pub enum CoroutineKind {
    Async {
        span: Span,
        closure_id: NodeId,
        return_impl_trait_id: NodeId,
    },
    Gen {
        span: Span,
        closure_id: NodeId,
        return_impl_trait_id: NodeId,
    },
    AsyncGen {
        span: Span,
        closure_id: NodeId,
        return_impl_trait_id: NodeId,
    },
}

Describes what kind of coroutine markers, if any, a function has.

Coroutine markers are things that cause the function to generate a coroutine, such as async, which makes the function return impl Future, or gen, which makes the function return impl Iterator.

Variants

Async

async, which returns an impl Future.

Fields

span: Span

closure_id: NodeId

return_impl_trait_id: NodeId

Gen

gen, which returns an impl Iterator.

Fields

span: Span

closure_id: NodeId

return_impl_trait_id: NodeId

AsyncGen

async gen, which returns an impl AsyncIterator.

Fields

span: Span

closure_id: NodeId

return_impl_trait_id: NodeId

Implementations

impl CoroutineKind

pub fn span(self) -> Span

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

pub fn closure_id(self) -> NodeId

pub fn return_id(self) -> (NodeId, Span)

In this case this is an async or gen return, the NodeId for the generated impl Trait item.

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.
