Understanding String, &str etc

Understanding String, &str etc

Hi,

I don't quite understand how strings work.

if I have a struct with a Struct

struct User {
name:String
}

then I can instantiate it as follows

let user = User {
name: "John".to_string()
}

If I leave out the to\_string() it won't compile

However if I do it this way and then do this:

format!("Name is {:?}", user.name);

Then the resulting string has escaped quotes like this:

"Name is \"John\""

What is going on here?


What is the difference between String and &str in Rust?
