Rust Deref coercion example

# Rust Deref coercion example

https://doc.rust-lang.org/std/ops/trait.Deref.html

```
use std::ops::Deref;

struct DerefExample<T> {
    value: T
}

impl<T> Deref for DerefExample<T> {
    type Target = T;

    fn deref(&self) -> &Self::Target {
        &self.value
    }
}

let x = DerefExample { value: 'a' };
assert_eq!('a', *x);
```

Deref coercion can be used in newtype:
```
struct MyI32(i32)

impl Deref for MyI32 {
    type Target = i32;

    fn deref(&self) -> &Self::Target {
        &self.0
    }
}
```
