This is actually a super tricky problem. We don't really have the capacity for more than one line of update-able information in Cargo right now, so we need to squeeze a lot of information into one line of output for Cargo. The main constraints this tries to satisfy are: * At all times it should be clear what's happening. Cargo shouldn't just hang with no output when downloading a crate for a long time, a counter ideally needs to be decreasing while the download progresses. * If a progress bar is shown, it shouldn't jump around. This ends up just being a surprising user experience for most. Progress bars should only ever increase, but they may increase at different speeds. * Cargo has, currently, at most one line of output (as mentioned above) to pack information into. We haven't delved into fancier terminal features that involve multiple lines of update-able output. * When downloading crates as part of `cargo build` (the norm) we don't actually know ahead of time how many crates are being downloaded. We rely on the calculation of unit dependencies to naturally feed into downloading more crates. * Furthermore, once we decide to download a crate, we don't actually know how big it is! We have to wait for the server to tell us how big it is. There doesn't really seem to be a great solution that satisfies all of these constraints unfortunately. As a result this commit implements a relatively conservative solution which should hopefully get us most of the way there. There isn't actually a progress bar but rather Cargo prints that it's got N crates left to download, and if it takes awhile it prints out that there are M bytes remaining. Unfortunately the progress is pretty choppy and jerky, not providing a smooth UI. This appears to largely be because Cargo will synchronously extract tarballs, which for large crates can cause a noticeable pause. Cargo's not really prepared internally to perform this work on helper threads, but ideally if it could do so it would improve the output quite a bit! (making it much smoother and also able to account for the time tarball extraction takes).
