std::execution::just_stopped

From cppreference.com
< cpp‎ | execution
 
 
 
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

Otherwise, no function call operator of execution::just_stopped_t participates in overload resolution.
