### What it does
This lint checks for `.to_string()` method calls on values of type `String`.
### Why is this bad?
The `to_string` method is also used on other types to convert them to a string.
When called on a `String` it only clones the `String`, which can be better expressed with `.clone()`.
### Example
```
// example code where clippy issues a warning
let msg = String::from("Hello World");
let _ = msg.to_string();
```
Use instead:
```
// example code which does not raise clippy warning
let msg = String::from("Hello World");
let _ = msg.clone();
```
