## minimal_rtti

### Synopsis

```c++
struct minimal_rtti : rtti {
    template<class Class>
    static constexpr bool is_polymorphic = false;

    template<typename Class>
    static auto static_type() -> type_id;
};
```

### Description

`minimal_rtti` is an implementation of the `rtti` policy that only uses static
type information.

`minimal_rtti` provides the only function strictly required for the `rtti`
policy.

This policy can be used in programs that call methods solely via
`virtual_ptr`{empty}s created with the "final" constructs. Virtual inheritance
is not supported. Classes are not required to be polymorphic.

### Members


#### is_polymorphic

```c++
template<class Class>
static constexpr bool is_polymorphic = false;
```

This policy does not support polymorphic classes.

#### static_type

```c++
template<class Class>
static auto static_type() -> type_id;
```

Returns the address of a local static `char` variable, cast to `type_id`.
