Nick TaylorI've been learning Rust on and off since last fall. I'm still not proficient in the language as I haven't dedicated as much time to the language as I'd like to. Still, I find pockets of time, like tonight, to dive in a bit.
A quick Google of "rust hot reloading" introduced me to the rust crate, cargo-watch. I installed it as per their instructions cargo install cargo-watch.
From there, I went into a rust project I'm working on and ran the following from the project's root from the command line, cargo watch -x 'run'.
And that was it! I was able to start up my program, and with every change, it reran automatically!
