Aleph::stl_detail Namespace Reference

Classes
struct	has_reverse_iterators
	Detect if a container has reverse iterators. More...
struct	has_reverse_iterators< T, std::void_t< decltype(std::declval< T >().rbegin()), decltype(std::declval< T >().rend())> >
struct	has_size
	Detect if a type has a size() method. More...
struct	has_size< T, std::void_t< decltype(std::declval< T >().size())> >
struct	is_std_hashable
	Detect if a type is hashable via std::hash. More...
struct	is_std_hashable< T, std::void_t< decltype(std::hash< T >{}(std::declval< T >()))> >

Functions
template<typename Container >
size_t	safe_size (const Container &c)
	Helper to get container size safely (returns 0 for containers without size())
template<typename Result , typename Container >
void	try_reserve (Result &result, const Container &c)
	Helper to reserve if possible.
template<typename Result >
void	try_reserve_n (Result &result, size_t n)
	Helper to reserve with a specific size if the result supports it.

Variables
constexpr size_t	ADAPTIVE_THRESHOLD = 64
	Threshold for switching from linear to hash-based algorithms.
