Function arrow::buffer::bitwise_bin_op_helper

pub fn bitwise_bin_op_helper<F>(
    left: &Buffer, 
    left_offset_in_bits: usize, 
    right: &Buffer, 
    right_offset_in_bits: usize, 
    len_in_bits: usize, 
    op: F
) -> Buffer where
    F: Fn(u64, u64) -> u64, 

Apply a bitwise operation op to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
