# Generics. Part 4

## Const generics

*const generic*s identical to C++ template parameters. With *const generics* you can do a lot of things e.g declare `SmallVector` type that will have some limit:

```csharp
struct SmallVector<T,var COUNT: int> {
    var array: T[COUNT];
}

var vector = SmallVector<int,32>();
```
