Function any

pub fn any(array: &BooleanArray) -> Option<bool>

Returns whether any of the values in the array are true.

The output is unknown (None) if the array contains any null values and no true values.

Example

use polars_arrow::array::BooleanArray;
use polars_arrow::compute::boolean_kleene::any;

let a = BooleanArray::from(&[Some(true), Some(false)]);
let b = BooleanArray::from(&[Some(false), Some(false)]);
let c = BooleanArray::from(&[None, Some(false)]);

assert_eq!(any(&a), Some(true));
assert_eq!(any(&b), Some(false));
assert_eq!(any(&c), None);
