basic_result &operator=(const basic_result &) - Boost.Outcome documentation

# `basic_result &operator=(const basic_result &)`

Copy assignment.

Requires: that `value_type` and `error_type` both implement copy assignment.

Complexity: If the `value_type` for both is present, uses `value_type`’s copy assignment operator, else either destructs or copy constructs `value_type` as appropriate. `error_type`’s copy assignment operator is always used. 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`.
