Yes, this is shitty code.

The functions/pipes are because I fairly regularly make changes to the way it works, and this way I can leave out of modify things without removing them entirely.

Save as cargo-installed in ~/.local/bin or somewhere in path, chmod +x, and you can use cargo installed
Alternatively:

git clone https://gist.github.com/Efreak/c2fad032110e2b65dcf625c20f889a2f ~/src/cargo-installed
ln -s ~/src/cargo-installed/cargo-installed.bsh ~/.local/bin/cargo-installed

And then you can update via git. Not that I expect there will be many updates here...
