## Detailed Description

GNU debug classes for public use.

## Typedef Documentation

A string of `char16_t`.

Definition at line 1312 of file debug/string.

## Enumeration Type Documentation

## _Distance_precision

enum __gnu_debug::_Distance_precision

The precision to which we can calculate the distance between two iterators.

Definition at line 52 of file helper_functions.h.

## Function Documentation

## __base()

template<typename _Iterator >

constexpr _Iterator __gnu_debug::__base | ( | _Iterator | __it | ) |

inline constexpr

Helper function to extract base iterator of random access safe iterator in order to reduce performance impact of debug mode. Limited to random access iterator because it is the only category for which it is possible to check for correct iterators order in the __valid_range function thanks to the < operator.

Definition at line 315 of file helper_functions.h.

## __check_singular()

template<typename _Tp >

constexpr bool __gnu_debug::__check_singular | ( | _Tp *const & | __ptr | ) |

inline constexpr

Non-NULL pointers are nonsingular.

Definition at line 138 of file helper_functions.h.

## __check_singular_aux()

bool __gnu_debug::__check_singular_aux | ( | const _Safe_iterator_base * | __x | ) |

inline

Iterators that derive from _Safe_iterator_base can be determined singular or non-singular.

Definition at line 168 of file safe_base.h.

References __gnu_debug::_Safe_iterator_base::_M_singular().

## __check_string() [1/2]

template<typename _CharT , typename _Integer >

const _CharT* __gnu_debug::__check_string | ( | const _CharT * | __s,
|  | _Integer | __n,
|  | const char * | __file,
|  | unsigned int | __line,
|  | const char * | __function
| ) |  |

inline

Checks that __s is non-NULL or __n == 0, and then returns __s.

Definition at line 57 of file debug/string.

## __check_string() [2/2]

template<typename _CharT >

const _CharT* __gnu_debug::__check_string | ( | const _CharT * | __s,
|  | const char * | __file,
|  | unsigned int | __line,
|  | const char * | __function
| ) |  |

inline

Checks that __s is non-NULL and then returns __s.

Definition at line 73 of file debug/string.

## __foreign_iterator_aux2() [1/2]

template<typename _Iterator , typename _Sequence , typename _Category , typename _OtherIterator , typename _OtherSequence , typename _OtherCategory >

bool __gnu_debug::__foreign_iterator_aux2 | ( | const _Safe_iterator< _Iterator, _Sequence, _Category > & | ,
|  | const _Safe_iterator< _OtherIterator, _OtherSequence, _OtherCategory > & | ,
|  | const _Safe_iterator< _OtherIterator, _OtherSequence, _OtherCategory > & |
| ) |  |

inline

Handle debug iterators from different types of container.

Definition at line 138 of file functions.h.

## __foreign_iterator_aux2() [2/2]

template<typename _Iterator , typename _Sequence , typename _Category , typename _OtherIterator >

bool __gnu_debug::__foreign_iterator_aux2 | ( | const _Safe_iterator< _Iterator, _Sequence, _Category > & | __it,
|  | const _Safe_iterator< _OtherIterator, _Sequence, _Category > & | __other,
|  | const _Safe_iterator< _OtherIterator, _Sequence, _Category > & |
| ) |  |

inline

Handle debug iterators from the same type of container.

Definition at line 127 of file functions.h.

## __get_distance()

template<typename _Iterator >

constexpr _Distance_traits<_Iterator>::__type __gnu_debug::__get_distance | ( | _Iterator | __lhs,
|  | _Iterator | __rhs,
|  | std::random_access_iterator_tag |
| ) |  |

inline constexpr

Determine the distance between two iterators with some known precision.

Definition at line 94 of file helper_functions.h.

## __valid_range() [1/3]

template<typename _InputIterator >

constexpr bool __gnu_debug::__valid_range | ( | _InputIterator | __first,
|  | _InputIterator | __last,
|  | typename _Distance_traits< _InputIterator >::__type & | __dist
| ) |  |

inline constexpr

Don't know what these iterators are, or if they are even iterators (we may get an integral type for InputIterator), so see if they are integral and pass them on to the next phase otherwise.

Definition at line 239 of file helper_functions.h.

References __valid_range_aux().

## __valid_range() [2/3]

template<typename _Iterator , typename _Sequence , typename _Category >

bool __gnu_debug::__valid_range | ( | const _Safe_iterator< _Iterator, _Sequence, _Category > & | __first,
|  | const _Safe_iterator< _Iterator, _Sequence, _Category > & | __last,
|  | typename _Distance_traits< _Iterator >::__type & | __dist
| ) |  |

inline

Safe iterators know how to check if they form a valid range.

Definition at line 942 of file safe_iterator.h.

## __valid_range() [3/3]

template<typename _Iterator , typename _Sequence >

bool __gnu_debug::__valid_range | ( | const _Safe_local_iterator< _Iterator, _Sequence > & | __first,
|  | const _Safe_local_iterator< _Iterator, _Sequence > & | __last,
|  | typename _Distance_traits< _Iterator >::__type & | __dist_info
| ) |  |

inline

Safe local iterators know how to check if they form a valid range.

Definition at line 409 of file safe_local_iterator.h.

## __valid_range_aux() [1/2]

template<typename _InputIterator >

constexpr bool __gnu_debug::__valid_range_aux | ( | _InputIterator | __first,
|  | _InputIterator | __last,
|  | std::__false_type |
| ) |  |

inline constexpr

We have iterators, so figure out what kind of iterators they are to see if we can check the range ahead of time.

Definition at line 195 of file helper_functions.h.

References std::__iterator_category(), and __valid_range_aux().

## __valid_range_aux() [2/2]

template<typename _Integral >

constexpr bool __gnu_debug::__valid_range_aux | ( | _Integral | ,
|  | _Integral | ,
|  | std::__true_type |
| ) |  |

inline constexpr

We say that integral types for a valid range, and defer to other routines to realize what to do with integral types instead of iterators.

Definition at line 154 of file helper_functions.h.
