Cargo is i) not a compiler, and ii) moving to the sparse index protocol [1] that do not fetch the whole index anyway. And even the older git protocol won't fetch the same data twice.

As a fairly avid Rust user I can say I'm excited to hear that! Just playing a little devil's advocate for fun.

That said I was moderately upset by this Friday after carefully assembling a development container for a project at work. Guess I'll have to make something persistent somewhere if I don't want to twiddle my thumbs before each build.

Cargo or not you probably should do that for your container, or use a shared cache (which I do at work for both Cargo and pip) ;-)
