How can I convert char to string?

Solution 1:

Use char::to_string, which is from the ToString trait:

fn main() {
    let string = 'c'.to_string();
    // or
    println!("{}", 'c');
}

Solution 2:

You can now use c.to_string(), where c is your variable of type char.

Solution 3:

Using .to_string() will allocate String on heap. Usually it's not any issue, but if you wish to avoid this and want to get &str slice directly, you may alternatively use

let mut tmp = [0u8; 4];
let your_string = c.encode_utf8(&mut tmp);
