Description

The Rust cargo coverage is failing with the following error:

warning: unused manifest key: package.edition

error[E0432]: unresolved import `num`
  --> arrow/src/array_ops.rs:22:5
   |
22 | use num::Zero;
   |     ^^^ did you mean `std::num`?
error[E0432]: unresolved imports `self::csv_crate::StringRecord`, `self::csv_crate::StringRecordsIntoIter`

   |

   |                       ^^^^^^^^^^^^  ^^^^^^^^^^^^^^^^^^^^^ no `StringRecordsIntoIter` in `csv`

30 | use serde_json::{json, Value};

   |     ^^^^ no `libc` in the root

   |
18 | use rand::{thread_rng, Rng};
   |     ^^^^ maybe a missing `extern crate rand;`?
...

perhaps because it doesn't recognize Rust 2018 edition.
