CallableTraits

template<typename F >

using TypeTraits::CallableTraits = ROOT::Detail::CallableTraitsImpl<F>

Extract types from the signature of a callable object.

The CallableTraits struct contains three type aliases:

• arg_types: a TypeList of all types in the signature, decayed through std::decay
• arg_types_nodecay: a TypeList of all types in the signature, including cv-qualifiers

InvokeResult_t

template<typename F , typename... Args>

using TypeTraits::InvokeResult_t = std::result_of_t<F(Args...)>

An adapter for std::invoke_result that falls back to std::result_of if the former is not available.

template<class T >

using TypeTraits::IsFloatNumeral = std::is_floating_point<T>
