Enum rustc_ast::ast::Async

pub enum Async {
    Yes {
        span: Span,
        closure_id: NodeId,
        return_impl_trait_id: NodeId,
    },
    No,
}

Variants

Yes

Fields

span: Span

closure_id: NodeId

return_impl_trait_id: NodeId

No

Implementations

impl Async

pub fn is_async(self) -> bool

pub fn opt_return_id(self) -> Option<(NodeId, Span)>

In this case this is an async 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.
