### Structs

```mist
pub struct Point
{
    i32 x,
    i32 y,
}

pub struct Generic<T>
{
    T value,
}
```

Fields can be public or private:

```mist
struct User
{
    pub str& name,
    i32 age,  // private
}
```

### Enums

```mist
pub enum Option<T>
{
    Some(T),
    None,
}

pub enum Message
{
    Quit,
    Move(i32, i32),
    Write { str& content, i32 length },
}
```

Enum variants can be:
- **Named** — `Variant`
- **Tuple** — `Variant(T1, T2)`
- **Struct** — `Variant { T1 field1, T2 field2 }`
