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.
