Function polars_arrow::compute::boolean_kleene::any

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

Available on crate feature compute_boolean_kleene only.

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);
