void void_t
A metafunction that always yields void, used for detecting valid types.
integral_constant< bool, true > true_type
The type used as a compile-time boolean with true value.
typename common_type< _Tp... >::type common_type_t
Alias template for common_type.
integral_constant< bool, false > false_type
The type used as a compile-time boolean with false value.
typename enable_if< _Cond, _Tp >::type enable_if_t
Alias template for enable_if.
constexpr const _Tp & min(const _Tp &, const _Tp &)
This does what you think it does.
ISO C++ entities toplevel namespace is std.
Properties of fundamental types.
static constexpr _Tp max() noexcept
static constexpr _Tp lowest() noexcept
Provides compile-time rational arithmetic.
Define a member typedef type only if a boolean constant is true.
chrono::duration represents a distance between two points in time
chrono::time_point represents a point in time as measured by a clock
