Detailed Description

template<typename Ty>
struct utilmm::identity< Ty >

Identity functor.

This functor correspond to the identity function. It is a function that will return exactly the same value as passed as argument. It also uses arg_traits to improve performances avoiding the copy of complex objects

Parameters:

Ty
