pub fn gen_vec(
n: usize,
) -> impl DoubleEndedIterator<Item = Vec<bool>> + ExactSizeIterator + FusedIterator
Expand description
Returns an Iterator
producing Vec<bool>
for each possible combinations of n
bool
s.
Note: If a Vec<bool>
is not needed
for each combination, then consider using gen_slice()
or gen_vec_slice()
instead.
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_vec(n).collect::<Vec<_>>();
assert_eq!(
combinations,
[
vec![false, false],
vec![true, false],
vec![false, true],
vec![true, true],
]
);
