Thanks for the suggestion. `AsRef<str>` is great when you want to accept any “string-like” type, especially for public helpers or utilities that aim for flexibility and ergonomics for all callers.
For a simple `greet`, I stick with `&str`: it already works with `&String` and string literals, keeps the signature clear, and avoids generic monomorphization.
I think you should better
```
pub fn greet<S: AsRef<str>>(text: S) {
let name = test.as_ref();
println!("Hello, {}!", name);
}
```
