-------------------------------
Summary: [Rust] Improve primitive types
Key: ARROW-3878
URL: https://issues.apache.org/jira/browse/ARROW-3878
Project: Apache Arrow
Issue Type: Improvement
Reporter: Chao Sun
Assignee: Chao Sun
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.
