nt-rs

nt-rs is an implementation of the NetworkTables revision 3 protocol in Rust using Tokio. Currently it is purely a client library. An API for creation of an NT server may come in the future.

Getting Started

This library can be found on https://crates.io and can be added to a project with nt = "0.1.0" Sample usages can be found in the examples/ directory

What is NetworkTables?

NetworkTables, or NT, is a TCP based protocol for key-value data storage. It is most used within code for FIRST Robotics Competition robots, for sharing data across the robot's network.

Examples

Connecting to a server

let mut nt = NetworkTables::connect("10.TE.AM.2:1735", "nt-rs-client")?;

Creating a server

let mut nt = NetworkTables::bind("0.0.0.0:1735", "nt-rs-server");

Websockets

nt 1.0.0 adds support for clients and servers communicating over websockets. This is locked behind the websocket feature.

Connecting to a websocket server

let mut nt = NetworkTables::connect_ws("ws://10.TE.AM.2:1735", "nt-ws-client")?;

Creating a websocket server

An existing NetworkTables server is capable of serving websockets if the program is compiled with the websocket feature. In cases where a websocket attempts to connect to a server that has not been configured for websocket clients, it will be sent an error message and the connection will be disconnected.
