Core language concepts

Defined in namespace std::experimental::ranges
Same	specifies that a type is the same as another type (concept)
DerivedFrom	specifies that a type is derived from another type (concept)
ConvertibleTo	specifies that a type is implicitly convertible to another type (concept)
CommonReference	specifies that two types share a common reference type (concept)
Common	specifies that two types share a common type (concept)
Integral	specifies that a type is an integral type (concept)
SignedIntegral	specifies that a type is an integral type that is signed (concept)
UnsignedIntegral	specifies that a type is an integral type that is not signed (concept)
Assignable	specifies that a type is assignable from another type (concept)
SwappableSwappableWith	specifies that a type can be swapped or that two types can be swapped with each other (concept)

Comparison concepts

Defined in namespace std::experimental::ranges
Boolean	specifies that a type can be used in Boolean contexts (concept)
WeaklyEqualityComparableWith	specifies that two types can be compared for equality using operators == and != (concept)
EqualityComparableEqualityComparableWith	specifies that operator == is an equivalence relation (concept)
StrictTotallyOrderedStrictTotallyOrderedWith	specifies that the comparison operators on the type yield a total order (concept)

Object concepts

Defined in namespace std::experimental::ranges
Destructible	specifies that an object of the type can be destroyed (concept)
Constructible	specifies that a variable of the type can be constructed from or bound to a set of argument types (concept)
DefaultConstructible	specifies that an object of a type can be default constructed (concept)
MoveConstructible	specifies that an object of a type can be move constructed (concept)
CopyConstructible	specifies that an object of a type can be copy constructed and move constructed (concept)
Movable	specifies that an object of a type can be moved and swapped (concept)
Copyable	specifies that an object of a type can be copied, moved, and swapped (concept)
Semiregular	specifies that an object of a type can be copied, moved, swapped, and default constructed (concept)
Regular	specifies that a type is regular, that is, it is both Semiregular and EqualityComparable (concept)

Callable concepts

Defined in namespace std::experimental::ranges
InvocableRegularInvocable	specifies that a callable type can be invoked with a given set of argument types (concept)
Predicate	specifies that a callable type is a Boolean predicate (concept)
Relation	specifies that a callable type is a binary relation (concept)
StrictWeakOrder	specifies that a Relation imposes a strict weak ordering (concept)
