Detailed Description

template<typename T>
class LIEF::result< T >

Wrapper that contains an Object (T) or an error.

The tl/expected implementation exposes the method value() to access the underlying object (if no error)

Typical usage is:

result<int> intval = my_function();
if (intval) {
 int val = intval.value();
} else { // There is an error
 std::cout << get_error(intval).message() << "\n";
}
