Replace push_str with the corresponding operator

[leonardo-m]

What it does

This (probably pedantic) link suggests to replace calls to .push_str() with the corresponding operator.

Advantage

Shorter and more to the point code. And scripting language programmerer (as Python) are used to using operators for this.

Drawbacks

I don't know if there are drawbacks.

Example

fn main() {
    let mut msg = String::from("Hello");
    msg.push_str(", world");
    println!("{msg}"); // Hello, world
}

Could be written as:

fn main() {
    let mut msg = String::from("Hello");
    msg += ", world";
    println!("{msg}"); // Hello, world
}

.push_str is more common IME. It's even in the main examples https://doc.rust-lang.org/std/string/struct.String.html#examples
