Function gen 

pub fn gen(
    n: usize,
) -> impl DoubleEndedIterator<Item = Bools> + ExactSizeIterator + FusedIterator

Returns an Iterator producing all possible combinations of n bools, in the form of individual Bools iterators.

Alternatively, use gen_slice() or gen_vec_slice() to receives &[bool] instead, where len() == n.

See also gen_const() for const generic variant.

See also implementation for more information about the Iterator implementation.

Panics

Panics if n is larger than the MAX number of supported variables. However, you likely have other problems, if you encounter this.

See also count(n) and is_supported(n).

Example

See crate root for more examples.

let n = 2;
let combinations = truth_values::gen(n)
    .map(|mut bools| {
        (bools.next().unwrap(), bools.next().unwrap())
    })
    .collect::<Vec<_>>();

assert_eq!(
    combinations,
    [
        (false, false),
        (true, false),
        (false, true),
        (true, true),
    ]
);
