Log Rust prints and panics to Luau for easy debugging.

Install

cargo add autput

Brief

When embedding Rust in Luau via Wasynth, there's no good default error handler or printing functionality. Rust panics cause mysterious error messages and printed messages go nowhere.

Autput aims to be a minimal useful product for sending panics and prints to Luau from Rust. You need only initialise Autput, and all the relevant panic handling and printing features are turned on for you automatically, so you can get to work right away.

fn main() {
	autput::connect();
	info!("This is an info message.");
	warn!("This is a warning message.");
	error!("This is an error message.");
	panic!("This is a panic.");
}

• Compatible with the log crate
• Send to print(), warn() (Roblox only), or your own Luau log functions
• Rust panics are redirected to Luau's error()

A note about println!

It isn't possible to redirect where standard output goes in Rust. As a result, Autput can't restore println!() functionality, or other similar hardcoded printing procedures.

Instead, you should use the log crate and its macros: info!(), warn!() etc.
