How do I convert a char to a String?

Question

Is there a succinct way to convert a char to a String in Rust other than:

let mut s = String::new();
s.push('c');

Answer 1

You use the to_string() method:

'c'.to_string()

Answer 2

Since Rust 1.46, String implements From<char>, so you can alternatively use:

String::from('c')

or, with type inference,

'c'.into()
