jabba_lib::jrandom

Function randint 

Source 
pub fn randint(lo: i32, hi: i32) -> i32
Expand description

Returns a random i32 from range [lo, hi], where both lo and hi are included.

Similar to Python’s random.randint().

§Examples

let number = jabba_lib::jrandom::randint(1, 6);

assert!(1 <= number && number <= 6);
