Method has_true

arrow-array/src/array/boolean_array.rs:187–196

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