explicit basic_outcome(const basic_outcome<A, B, C, D> &)
Explicit converting copy constructor from compatible basic_outcome. Calls void hook_outcome_copy_construction(T *, U &&) noexcept
with this and the input.
Requires: predicate::enable_compatible_conversion<A, B, C, D> is true.
Complexity: Same as for the copy constructors of the underlying types. Constexpr, triviality and noexcept of underlying operations is propagated.
Guarantees: If an exception is thrown during the operation, the object is left in a partially completed state, as per the normal rules for the same operation on a struct.
