Defined in header <execution>
execution::sender auto into_variant( execution::sender auto snd );		(since C++26)

Parameters

snd

-

input sender which can send multiple sets of values depending on runtime conditions.

Return value

Returns a sender that sends a variant of tuples of all the possible sets of types sent by the input sender. The helper function turns them into a single variant value.
