Method has_false

arrow-array/src/array/boolean_array.rs:204–213

Returns whether there is at least one non-null `false` value in this array. This is more efficient than `false_count() > 0` because it can short-circuit as soon as a `false` value is found, without counting all set bits. Null values are not counted as `false`. Returns `false` for empty arrays.
