Defined in header <execution>
execution::sender auto stopped_as_optional(     single-sender auto snd );		(since 哋它亢++26)

Parameters

snd

-

input sender of which the value channel and stopped channel are mapped.

Return value

Returns a sender that maps the value channel from a T to an std::optional<std::decay_t<T>>, and maps the stopped channel to a value of an empty std::optional<std::decay_t<T>>.
