A customisation point that delivers a value to a receiver.
constexpr unspecified set_value = unspecified;
The name execution::set_value denotes a customisation point
object. The expression execution::set_value(R, Vs...) for some
subexpressions R and Vs... is expression-equivalent
to:
R.set_value(Vs...), if that expression is valid. If the
function selected does not send the value(s) Vs... to the
receiver R's value channel, the program is ill-formed with
no diagnostic required.
set_value(R, Vs...), if that expression is valid,
with overload resolution performed in a context that includes the declaration
void set_value(); and that does not include a declaration
of execution::set_value. If the function selected by overload
resolution does not send the value(s) Vs... to the receiver
R's value channel, the program is ill-formed with no diagnostic
required.
execution::set_value(R, Vs...) is ill-formed.
