A set of utilities implementing the network protocol used by Witcher 3 written in Rust. The repository includes:

• rw3d_net - core library implementing the network protocol and known messages
• rw3d_net_client - client for rw3d_net
• rw3d_cli - Command Line Interface tool utilizing the aformentioned client

rw3d_cli is intended for Witcher 3 modders who make mainly script based mods. The main features of it include recompiling game scripts at run time, monitoring scripts log and remotely running exec functions in game, which can greatly help during mod development.

Parts of this code are based off of Wolvenkit modding tool by Traderain, rfuzzo and others https://github.com/WolvenKit/WolvenKit
