std::execution::just_stopped
Defined in header <execution>

||
inline constexpr just_stopped_t just_stopped{}; struct just_stopped_t { /*unspecified*/ }; |
(since C++26) (customization point object) |
|
Call signature |
||
execution::sender auto just_stopped(); |
(since C++26) | |
A sender factory that returns a sender which completes immediately by calling the receiver’s set_stopped()
.
The expression just_stopped() is expression-equivalent to /*make-sender*/(just_stopped)
Customization point objects
The name execution::just_stopped
denotes a customization point object, which is a const function object of a literal semiregular
class type. The cv-unqualified version of its type is a tag type denoted as execution::just_stopped_t
.
All instances of execution::just_stopped_t
are equal. The effects of invoking different instances of type execution::just_stopped_t
on the same arguments are equivalent, regardless of whether the expression denoting the instance is an lvalue or rvalue, and is const-qualified or not (however, a volatile-qualified instance is not required to be invocable). Thus, execution::just_stopped
can be copied freely and its copies can be used interchangeably.
Given a set of types Args...
, if std::declval<Args>()... meet the requirements for arguments to execution::just_stopped
above, execution::just_stopped_t
models
- std::invocable<execution::just_stopped_t, Args...>,
- std::invocable<const execution::just_stopped_t, Args...>,
- std::invocable<execution::just_stopped_t&, Args...>, and
- std::invocable<const execution::just_stopped_t&, Args...>.
Otherwise, no function call operator of execution::just_stopped_t
participates in overload resolution.
