Struct CoroutineMarker 

pub struct CoroutineMarker {
    pub kind: CoroutineKind,
    pub span: Span,
    pub closure_id: NodeId,
    pub return_impl_trait_id: NodeId,
}

Describes the coroutine markers a function/closure 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.

Fields

kind: CoroutineKind

span: Span

closure_id: NodeId

return_impl_trait_id: NodeId

The NodeId for the generated impl Trait item.

Implementations

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.
