Variable Acts::Concepts::has_member

Variable Documentation

template<typename T, template<class...> class M, typename V>
constexpr bool Acts::Concepts::has_member = identical_to<V, M, T>

Helper to assert if a member of a given type exists.

Basically only calls into identical_to but is nicer to read.

Template Parameters
  • T: The type to check existence of member on.

  • M: The member type trait

  • V: The type that the member is supposed to have.
