Function yes 

pub fn yes(string: impl Display) -> bool

Determines if a value is a form of yes.

Returns true when the value is and/or contains (see examples for clarification) "y", "yes", true or 1.

Examples

yes should be yes:

assert!(yn::yes("y"));
assert!(yn::yes("yes"));
assert!(yn::yes("true true true really true"));
assert!(yn::yes("double up to make sure, yes yes y y true true 1 1"));
assert!(yn::yes("definitely yes"));

should definitely not be yes:

assert!(!yn::yes("no"));
assert!(!yn::yes("this is definitely a no."));
assert!(!yn::yes("false"));
