Syntax

template<typename T>  
struct TIdentity  
Copy full snippet

template<typename T> struct TIdentity

Remarks

Returns the same type passed to it. This is useful in a few cases, but mainly for inhibiting template argument deduction in function arguments, e.g.:

template void Func1(T Val); // Can be called like Func(123) or Func(123);

template void Func2(typename TIdentity::Type Val); // Must be called like Func(123)

Equivalent to C++20's std::type_identity.
