# `impl Trait`
|
||
|
|
|
||
|
|
Similar to trait bounds, an `impl Trait` syntax can be used in function
|
||
|
|
arguments and return values:
|
||
|
|
|
||
|
|
```rust,editable
|
||
|
|
use std::fmt::Display;
|
||
|
|
|
||
|
|
fn get_x(name: impl Display) -> impl Display {
|
||
|
|
format!("Hello {name}")
|
||
|
|
}
|
||
|
|
|
||
|
|
fn main() {
|
||
|
|
let x = get_x("foo");
|
||
|
|
println!("{x}");
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
* `impl Trait` cannot be used with the `::<>` turbo fish syntax.
|
||
|
|
* `impl Trait` allows you to work with types which you cannot name.
