Classes
struct	reference_wrapper< T >
	reference_wrapper is a class template that wraps a reference in a copyable, assignable object. It is frequently used as a mechanism to store references inside standard containers (like etl::static_vector) which cannot normally hold references. Specifically, reference_wrapper is a CopyConstructible and CopyAssignable wrapper around a reference to object or reference to function of type T. Instances of reference_wrapper are objects (they can be copied or stored in containers) but they are implicitly convertible to T&, so that they can be used as arguments with the functions that take the underlying type by reference. If the stored reference is Callable, reference_wrapper is callable with the same arguments. More...
