# std::bit_xor

From cppreference.com
< cpp‎ | utility‎ | functional

Defined in header `<functional>` |  |

template< class T > struct bit_xor; |  | (until C++14)
template< class T = void > struct bit_xor; |  | (since C++14)

Function object for performing bitwise XOR. Effectively calls operator^ on type `T`.

### [edit] Specializations

The standard library provides a specialization of `std::bit_xor` when `T` is not specified, which leaves the parameter types and return type to be deduced.
bit_xor<void> | function object implementing x ^ y deducing argument and return types (class template specialization) [edit]
| (since C++14)

### [edit] Member types

Type | Definition
`result_type` | `T`
`first_argument_type` | `T`
`second_argument_type` | `T`

### [edit] Member functions

operator() | returns the result of bitwise XOR of two arguments (public member function)

# std::bit_xor::operator()

T operator()( const T& lhs, const T& rhs ) const; |  | (until C++14)
constexpr T operator()( const T& lhs, const T& rhs ) const; |  | (since C++14)

Returns the result of bitwise XOR of `lhs` and `rhs`.

### Parameters

lhs, rhs | - | values to compute bitwise XOR of

### Return value

The result of lhs ^ rhs.

### Exceptions

(none)

### Possible implementation

    constexpr T operator()(const T &lhs, const T &rhs) const
    {
        return lhs ^ rhs;
    }
