Show HN: Typed-arrow – compile‑time Arrow schemas for Rust

Hi community, we just released https://github.com/tonbo-io/typed-arrow.

When working with arrow-rs, we noticed that schemas are declared at runtime. This often leads to runtime errors and makes development less safe.

typed-arrow takes a different approach:

- Schemas are declared at compile time with Rust’s type system.

- This eliminates runtime schema errors.

- And introduces no runtime overhead — everything is checked and generated by the compiler.

If you’ve run into Arrow runtime schema issues, and your schema is stable (not defined or switched at runtime), this project might be useful.
