Friends And Related Symbol Documentation

any

constexpr range any ( )

friend

range class builder function. Creates a range [0, inf].

Returns

Built range class instance.

Definition at line 163 of file range.hpp.

at_least

constexpr range at_least ( const count_type  n )

friend

range class builder function. Creates a range [n, inf).

Parameters

n	The lower bound.

Returns

Built range class instance.

Definition at line 128 of file range.hpp.

less_than

constexpr range less_than ( const count_type  n )

friend

range class builder function. Creates a range [0, n - 1].

Parameters

n	The upper bound

Returns

Built range class instance.

Definition at line 146 of file range.hpp.

more_than

constexpr range more_than ( const count_type  n )

friend

range class builder function. Creates a range [n + 1, inf).

Parameters

n	The lower bound.

Returns

Built range class instance.

Definition at line 137 of file range.hpp.

operator<<

std::ostream & operator<< ( std::ostream &  os, const range &  r  )

friend

Definition at line 92 of file range.hpp.

operator<=>

constexpr std::weak_ordering operator<=> ( const count_type  n, const range &  r  )

friend

Determines the ordering of the count against a range instance.

For a [lower, upper] range and the count n the returned value is:

• less if n < lower,
• equivalent if n >= lower and n <= upper,
• greater if n > upper.

Parameters

n	The value count to order.

Returns

Ordering relationship between the count and the range.

Definition at line 80 of file range.hpp.

up_to

constexpr range up_to ( const count_type  n )

friend

range class builder function. Creates a range [0, n].

Parameters

n	The upper bound

Returns

Built range class instance.

Definition at line 155 of file range.hpp.
