The coroutine support library defines several types that provide compile and run-time support for coroutines.

Contents

[edit] Coroutine traits

Defined in header <coroutine>
trait type for dicovering coroutine promise types
(class template) [edit]

[edit] Coroutine handle

Defined in header <coroutine>
used to refer to a suspended or executing coroutine
(class template) [edit]

[edit] No-op coroutines

Defined in header <coroutine>
creates a coroutine handle that has no observable effects when resumed or destroyed
(function) [edit]
used for coroutines with no observable effects
(class) [edit]
std::coroutine_handle<std::noop_coroutine_promise>, intended to refer to a no-op coroutine
(typedef) [edit]

[edit] Trivial awaitables

Defined in header <coroutine>
indicates that an await-expression should never suspend
(class) [edit]
indicates that an await-expression should always suspend
