Function take_primitive

arrow-select/src/take.rs:400–411

`take` implementation for all primitive arrays This checks if an `indices` slot is populated, and gets the value from `values` as the populated index. If the `indices` slot is null, a null value is returned. For example, given: values: [1, 2, 3, null, 5] indices: [0, null, 4, 3] The result is: [1 (slot 0), null (null slot), 5 (slot 4), null (slot 3)]

    values: &PrimitiveArray<T>,
    indices: &PrimitiveArray<I>,
)

///     indices: [0, null, 4, 3]
/// The result is: [1 (slot 0), null (null slot), 5 (slot 4), null (slot 3)]
