> Can I get iterm2 with bash and vscode and rust?
Not really. The best dev experience I have with the iPad is using Blink to mosh into (the mobility mosh offers over SSH is key for me) a server, which lets me run whatever I want on it. But if you're developing GUI applications, it's not really that great.
You can use something like Working Copy for git and Textastic for editing programs on the iPad, but it's not really a proper IDE (even a light IDE) just a syntax aware editor. If I'm not using emacs on the server, I use those for my code editing purposes.
