Returns a new dictionary with the same keys as the current instance but with a different set of dictionary values This can be used to perform an operation on the values of a dictionary # Panics Panics if `values` has a length less than the current values ``` # use std::sync::Arc; # use arrow_array::builder::PrimitiveDictionaryBuilder; # use arrow_array::{Int8Array, Int64Array, ArrayAccessor};
