## Orphan Rules ## Orphan Rules
We can’t implement external traits on external types. For example, we can’t implement the `Display` trait on `Vec<T>` within our own crate, because `Display` and `Vec<T>` are defined in the standard library and aren’t local to our crate.

This restriction is often called as the orphan rule, so named because the parent type is not present. This rule ensures that other people’s code can’t break your code and vice versa.

It’s possible to get around this restriction using the newtype pattern, which involves creating a new type in a tuple struct. It’s possible to get around this restriction using the newtype pattern, which involves creating a new type in a tuple struct.
