# Trait Bounds
|
||
|
|
|
||
|
|
When working with generics, you often want to limit the types. You can do this
|
||
|
|
with `T: Trait` or `impl Trait`:
|
||
|
|
|
||
|
|
```rust,editable
|
||
|
|
fn duplicate<T: Clone>(a: T) -> (T, T) {
|
||
|
|
(a.clone(), a.clone())
|
||
|
|
}
|
||
|
|
|
||
|
|
// struct NotClonable;
|
||
|
|
|
||
|
|
fn main() {
|
||
|
|
let foo = String::from("foo");
|
||
|
|
let pair = duplicate(foo);
|
||
|
|
}
|
||
|
|
```
