basic_result(const basic_result &) - Boost.Outcome documentation

# `basic_result(const basic_result &)`

Copy constructor.

Requires: that `value_type` and `error_type` both implement a copy constructor.

Complexity: Same as for `value_type`’s and `error_type`’s copy constructors. 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`.
