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 block written by the user.

Fn

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