War3StatsObserver

Rust bindings for the Warcraft 3 Stats Observer API memory map. Great for a streaming or build order overlay.

Top level binding to access everything is ObserverData struct.

let od = match ObserverData::new() {
    Ok(od) => od,
    Err(e) => {
        eprintln!("Error opening observer API. Is Warcraft3 running? Error: {e:?}");
        // handle error
    }
};

A refresh rate of 0 (measured in milliseconds) disables the API. Default rate is 500ms when using new(), but you can change it.

The structs are packed due to how the memory map is laid out. This makes it a pain to work with certain fields of the structs at times because rust does not allow a reference to an unaligned field. To get around this, you can make a copy in place by wrapping a field in {}

println!("version: {}", { od.version });
