# \_\_gnu\_debug::\_Safe\_vector(3)

Base class for Debug Mode vector.

## NAME

\_\_gnu\_debug::\_Safe\_vector\< \_SafeSequence, \_BaseSequence \> - Base class for Debug Mode vector.

## SYNOPSIS

\#include \<vector\>

Inherited by **std::\_\_debug::vector\< \_Tp, \_Allocator \>**.

### Protected Member Functions

constexpr **\_Safe\_vector** (\_Safe\_vector &&\_\_x) noexcept\
 constexpr **\_Safe\_vector** (const \_Safe\_vector &) noexcept\
 constexpr **\_Safe\_vector** (size\_type \_\_n) noexcept\
 bool **\_M\_requires\_reallocation** (size\_type \_\_elements) const noexcept\
 constexpr void **\_M\_update\_guaranteed\_capacity** () noexcept\
 constexpr \_Safe\_vector & **operator=** (\_Safe\_vector &&\_\_x) noexcept\
 constexpr \_Safe\_vector & **operator=** (const \_Safe\_vector &) noexcept\

### Protected Attributes

size\_type **\_M\_guaranteed\_capacity**\

## Detailed Description

### template\<typename \_SafeSequence, typename \_BaseSequence\>

class \_\_gnu\_debug::\_Safe\_vector\< \_SafeSequence, \_BaseSequence \>"Base class for Debug Mode vector.

Adds information about the guaranteed capacity, which is useful for detecting code which relies on non-portable implementation details of the libstdc++ reallocation policy.
