    typename Return,
    typename Executor>
struct coro_traits

Types

Name	Description
completion_handler	Completion handler type used by async_resume.
error_type	The error type of the coroutine. void for noexcept.
input_type	The value that can be passed into a symmetrical cororoutine. void if asymmetrical.
result_type	The type received by a co_await or async_resume. It's a combination of yield and return.
return_type	The type that can be passed out through a co_return.
signature_type	The signature used by the async_resume.
yield_type	The type that can be passed out through a co_yield.

Data Members

Name	Description
is_noexcept [static]	Whether or not the coroutine is noexcept.

Template parameter Yield specifies type or signature used by co_yield, Return specifies the type used for co_return, and Executor specifies the underlying executor type.
