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