My son (Toke, 7 years old) and I have long talked about making our own computer game.
Reading a file in C++ is almost identical to how it’s done C.
To create a plugin system in C++ you need three things.
To parse json in Rust you need a library. The one used here is called rustc-serialize.
In C++ there are no built-in ways to handle json. However there are many open source libraries to help you.
