n2o4

The n2o4 crate provides safe, idiomatic Rust bindings to the APIs of cFE and OSAL, the libraries of the Core Flight System (cFS).

IMPORTANT NOTE

This is a work in progress. While enough has been written to allow some classes of cFS application to be written, bindings for many parts of the API don't currently exist.

If you need or want to use some part of the API for which a binding doesn't exist yet, consider helping to flesh out the crate!

Limitations

Currently, n2o4 only supports the following:

• cFE tag v7.0.0-rc4
• OSAL tag v6.0.0-rc4

Extending support to other versions is an open issue (BlackCAT-Cubesat/n2o4#1).

Minimum Rust version

n2o4 requires Rust 1.64.0 or newer.

Using this crate in your cFS app

See USING.md for how to set everything up to use n2o4 (and Rust in general) in your cFS application.

Also, take a look at a sample app demonstrating the use of n2o4.

About the name

N₂O₄ is the chemical formula for dinitrogen tetroxide (aka nitrogen tetroxide). As cFS is intended for spacecraft flight software, and the Rust community has a long history of oxidation-related names, it seems appropriate to give this crate the name of a rocket propellant—one that's an oxidizer.
