Function random_string 

Source 
pub fn random_string(len: usize) -> String
Available on crate feature id only.
Expand description

Generate a random string of length len using the same 36-char alphabet as Node’s id.randomString(len): 0-9 plus qwertyuioplkjhgfdsazxcvbnm (keyboard order).

let s = bento_kit::id::random_string(20);
assert_eq!(s.len(), 20);
