> Currently we simply uses Rust's native types as primitive types, and relies
> on macros such as
> [this|https://github.com/apache/arrow/blob/master/rust/src/array.rs#L298] to
> link the Arrow data type with the native type. A better approach may be to
> define richer primitive types which contain both the Arrow type and the Rust
> native type, as well as other information such as type's bit width,
> precision, etc.
