Function mock

pub fn mock(text: &str) -> String

Returns a String with the letters changed to alternate between uppercase and lowercase.

All instances of the letters L and i are set to uppercase and lowercase, respectively. The case of the first letter in the input is determined based on where either aforementioned letter first appears, defaulting to lowercase if neither appears in the text.

The capitalisation in the input is not preserved, although all non-ascii and non-alphabetic characters are preserved as-is.

Examples

let hello = "Hello, world!";
let ironic_hello = fancy_mocker::mock(hello);
 
assert_eq!(ironic_hello, "HeLLo, WoRLd!");
