Review comment:
This is an example of type inferences that would become compiler errors
with the inclusion of the `prettytable-rs` crate. I have fixed this code, but
the original error being generated was:
```
error[E0282]: type annotations needed
--> parquet/src/encodings/rle.rs:833:26
|
833 | Standard.sample_iter(&mut
rng).take(seed_len).collect();
| ^^^^^^^^^^^ cannot infer type for `T`
```
