struct bit_not;
|
| | (since C++14) |
Function object for performing bitwise NOT. Effectively calls operator~ on type T.
Specializations
| The standard library provides a specialization of std::bit_not when T is not specified, which leaves the parameter types and return type to be deduced.
| | function object implementing ~x deducing argument and return types
(class template specialization) |
| (since C++14) |
Member types
| Type | Definition |

result_type | T |
argument_type | T |
Member functions
| | returns the result of bitwise NOT of its argument
(public member function) |
std::bit_not::operator()
1 | constexpr T operator()( const T& arg ) const;
|
| | |
Returns the result of bitwise NOT of arg.
Parameters
| arg | - | value to compute bitwise NOT of |
Return value
The result of ~arg.
Exceptions
(none).
