Cargo start-watch Script with Tests and Clippy for Rust Projects

This is the script I use when I'm working on rust projects:

cargo watch -c -x 'test solo -- --nocapture && cargo test -- --nocapture && cargo clippy && cargo run'

It does the following:

Watches for file changes and runs the various sub-processes when one occurs
clears the screen
Runs all tests with "solo" in the name
If all "solo" tests run, the full test suite is run
If all tests pass cargo clippy is run to look for possible improvements to the code
Finally, the project is run

Adding that to a script file called start-watcher is the first thing I do in every project. In terms of code to quality of life improvement it's way up there on the ratio.

The solo approach is one of my favorites. It's the reverse of adding ignore to a test to take it out of the mix. Prepending tests with solo- runs them in the first batch. Makes it easier to see the results of one test instead of them being mushed in with all the others.
