List of utility concepts used in the library, that allows to check and constrain iterators, pointers, const correctness management, ranges, etc.

Collaboration diagram for Utility Concepts:

Concepts
concept	vcl::IsConst
	The IsConst concept is satisfied if T satisfies one of the following conditions:

concept	vcl::IteratorConcept
	The IteratorConcept is satisfied if T is an input or output iterator.

concept	vcl::InputIterator
	The InputIterator concept is satisfied if T is an input iterator that implements the `operator*` returning a value convertible to V.

concept	vcl::OutputIterator
	The OutputIterator concept is satisfied if T is an output iterator that implements the `operator*` returning a reference to V.

concept	vcl::IteratesOverClass
	The IteratorOverClass concept is satisfied if T is an iterator having its `value_type` that is a class.

concept	vcl::IteratesOverPointer
	The IteratorOverPointer concept is satisfied if T is an iterator having its `value_type` that is a pointer.

concept	vcl::IsPointer
	The IsPointer concept is satisfied if T is a Pointer, even if the type T is a reference to a pointer.

concept	vcl::IsSharedPointer
	The IsSharedPointer concept is satisfied if T is a shared pointer.

concept	vcl::IsAnyPointer
	The IsAnyPointer concept is satisfied if T is a Pointer or a shared pointer.

concept	vcl::IsPointerToConst
	The IsPointerToConst concept is satisfied if T is a Pointer to a constant object.

concept	vcl::IsSharedPointerToConst
	The IsSharedPointerToConst concept is satisfied if T is a shared pointer to a constant object.

concept	vcl::IsAnyPointerToConst
	The IsAnyPointerToConst concept is satisfied if T is a Pointer or a shared pointer to a constant object.

concept	vcl::Cloneable
	Concept that is evaluated true if T is a cloneable object.

concept	vcl::Range
	Utility concept that is evaluated true if T is a range, e.g. if has a begin and an end.

concept	vcl::RangeOf
	Utility concept that is evaluated true the Range R has a value_type that is exactly T.

concept	vcl::InputRange
	Utility concept that is evaluated true the Range R is an Input Range and has a value_type that is convertible to T.

concept	vcl::OutputRange
	Utility concept that is evaluated true the Range R is an Output Range and has a value_type that is T.

concept	vcl::OutputStreamable
	Concept that is evaluated true if T is an output streamable type.

concept	vcl::InputStreamable
	Concept that is evaluated true if T is an input streamable type.

concept	vcl::Serializable
	Concept that is evaluated true if T is serializable.

concept	vcl::IntegralOrEnum
	Concept for types that can be used as indices.

concept	vcl::NonBoolIntegralOrEnum
	Concept for types that can be used as indices, excluding bool.

concept	vcl::IsClass
	Concept that is evaluated true if T is a class.

concept	vcl::IsNotClass
	Concept that is evaluated true if T is not a class.

concept	vcl::IsInstantiable
	Concept that is evaluated true if the templated type C is instantiable with type T, i.e., C<T> is a valid type.
