Function fixed 

pub fn fixed(val: u128) -> impl FnMut(&State) -> u128

A pre-canned delegate that always parrots a given value.

Examples

use tinyrand::Rand;
use tinyrand_alloc::{Mock, fixed};

let mut mock = Mock::default().with_next_u128(fixed(42));
assert_eq!(42, mock.next_u64());
assert_eq!(42, mock.next_u64());
