## Versioning / Releases
-Unlike many other crates in the Rust ecosystem which spend extended time in
"pre 1.0.0" state, releasing versions 0.x, the arrow-rs crate follows the
versioning scheme of the overall [Apache Arrow](https://arrow.apache.org/)

integration tested with each other.

undefined behavior, and it is especially easy to misuse code in modules named
above. For an example, as described in [the arrow2
crate](https://github.com/jorgecarleitao/arrow2#why), the following code
compiles, does not panic, but results in undefined behavior:
