@alippai has an improvement for string formatting decimal values in #406
If he adds the method to DecimalArray in #406 (comment) it would be neat to also add it to the doc test.

You'll be able to add assert_eq!("8887.000000", decimal_array.value_as_string(0)); when I finish the PR. Also I'd keep the assert_eq!(8_887_000_000, decimal_array.value(0)); example (to show the values are i128 values)

I think using the DecimalBuilder to construct a DecimalArray may make for a better example:
For example, here: https://github.com/apache/arrow-rs/blob/master/arrow/src/array/builder.rs#L2856
