Simple, high-level and (somehow) type-safe wrapper for [Valve GameNetworkingSockets](https://github.com/ValveSoftware/GameNetworkingSockets).

- [**Have a quick look at the reliable chat client/server implementation**](./example/src/main.rs)

The library does not require your application to be running with Steam and this wrapper is intended to wrap the open-source version only.

Some features might be missing, if you are interested to introduce more abstraction, feel free to open a PR/Issue.

Libraries:
- `gns-sys` is the C++ library from Valve compiled with bindings generated (the library is directly compiled by cargo so you don't need to have it already installed).
- `gns` is the high level, type-safe Rust wrapper.

## Building

A few system libraries/tools are required in order to compile the C++ library as part of `gns-sys`.

System libraries required:
- `clang`
- `protobuf`
- `openssl`
- `abseil` (if using a recent version of protobuf)

Tools required to be in $PATH:
- `git`
- `protobuf-compiler`

### Windows

Building on Windows uses [vcpkg](https://github.com/microsoft/vcpkg) in manifest mode to gather and
build dependencies. As such, the only requirement on Windows is to have `clang` installed and `git`
available in $PATH.

### macOS

#### Apple Silicon

- Install these dependencies:
```bash
brew install openssl@3 protobuf@21
```

- Verify you’re using Protobuf 21.x:
```bash
protoc --version   # should print 3.21.x
```

- If you see errors like “no member named ‘c_str’ in ‘std::string_view’”, you’re likely picking up a newer Protobuf. Either unlink the newer one or point CMake to 21.x:
```bash
# Only if needed
brew unlink protobuf
brew link --overwrite protobuf@21   # add --force if keg-only warns
```

#### Intel

Untested on Intel.
