Defined in header <execution>
execution::sender auto on( execution::scheduler auto sched,                            execution::sender auto snd );		(since C++26)

Parameters

sched	-	provides execution agent on which the sender will be executed
snd	-	work to be executed on the execution resource associated with sched

Return value

Returns a sender which, when started, will start the provided sender on an execution agent belonging to the execution resource associated with the provided scheduler.

The returned sender has no completion schedulers.
