Hello! Thanks for writing this, looks super neat! :)

I had a problem installing this just now, perhaps I am missing something obvious, but just wanted to file this in case it is helpful

Details below, let me know if you would like more information :)

Hello! Thanks for writing this, looks super neat! :)

Thank you for the feedback!

Which version of Rust are you using? This feature should have been stable for quite some time, judging by the time the referenced ticket was closed.

[sharkdp]

Rust 1.29 and higher should work. I haven't tested anything before that.

[njtierney]

Ah yes, I should have checked the version of rust I was using - I was on 1.24.1, which looks like it didn't have rustup, so I uninstalled with brew uninstall rust, and then used the instructions here: https://www.rust-lang.org/en-US/install.html to reinstall.

works great now, thanks for your help! :)
