Expand description
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
.
async
, which returns an impl Future
.
