[−][src]Crate const_tweaker

Runtime const tweaking

This library starts a web server at http://127.0.0.1:9938 where you can change the values of const variables in your crate.

f64 & bool are the types that are currently supported.

Example

// Tweak `VALUE` when running in debug mode
const_tweaker::tweak! {
    VALUE: f64 = 0.0;
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize the server at 'http://127.0.0.1:9938' when running in debug mode
    #[cfg(debug_assertions)]
    const_tweaker::run()?;

    // Enter a GUI/Game loop
    loop {
        // ...

        // Print the constant value that can be changed from the website.
        println!("VALUE: {}", VALUE);
    }

    Ok(())
}
