< cpp‎ | header

This header is part of the experimental library.


Name Description
(library fundamentals TS)
exception that is thrown by a failed any_cast.
(library fundamentals TS)
Objects that hold instances of any type that satisfies the ValueType requirements.


swaps two any instances
type-safe access to the contained object
(function template)
