[exec.inline.scheduler]

namespace std::execution { class inline_scheduler { class inline-sender; / exposition only template<receiver R> class inline-state; / exposition only public: using scheduler_concept = scheduler_t; constexpr inline-sender schedule() noexcept { return {}; } constexpr bool operator=(const inline_scheduler&) const noexcept = default; }; }

inline_scheduler is a class that models scheduler ([exec.sched]).

All objects of type inline_scheduler are equal.

inline-sender is an exposition-only type that satisfies sender .

The type completion_signatures_of_t<inline-sender> is completion_signatures<set_value_t()>.

Let sndr be an expression of type inline-sender, let rcvr be an expression such that receiver_of<decltype(rcvr)), CS> is true where CS is completion_signatures<set_value_t()>, then:

(3.1)
the expression connect(sndr, rcvr) has type inline-state<remove_cvref_t<decltype(rcvr))> and is potentially-throwing if and only if ((void)sndr, auto(rcvr)) is potentially-throwing, and
(3.2)
the expression get_completion_scheduler<set_value_t>(get_env(sndr)) has type inline_scheduler and is potentially-throwing if and only if get_env(sndr) is potentially-throwing.

Let o be a non-const lvalue of type inline-state<Rcvr>, and let REC(o) be a non-const lvalue reference to an object of type Rcvr that was initialized with the expression rcvr passed to an invocation of connect that returned o, then:

(4.1)
the object to which REC(o) refers remains valid for the lifetime of the object to which o refers, and
(4.2)
the expression start(o) is equivalent to set_value(std::move(REC(o)).
