Generics typically refer to the use of templates to create code that works with various data types in a type-safe manner. Templates allow you to write generic functions or classes with placeholders for data types.
// generics_overview_2.cpp // compile with: /clr generic <typename T> ref class GenericType {}; ref class ReferenceType {}; value struct ValueType {}; int main() { GenericType<ReferenceType^> x; GenericType<ValueType> y; } Type Parameters Type parameters in a generic class are treat...
Templates specialized in two different assemblies with the same type arguments are considered by the runtime to be different types. Generics are generated as a single piece of executable code which is used for all reference type arguments (this is not true for value types, which have a unique...
let mut out: Self::Output = Default::default(); for r in 0..N { for c in 0..M { for l in 0..L { out.0[r][l] = out.0[r][l] + self.0[r][c] * rhs.0[c][l]; } } } out } } type Vector<T, const N: usize> = Matrix<T, N, 1usize>; fn main() { let...

Here's a C++ example with two mixin types: one that allows you to mix in the property of having a time stamp, and another that mixes in a serial number for each object instance: //: generics/Mixins.cpp #include <string> #include <ctime> ...
