Some form of CLI UI for "progress"

[andrewpatto]

Will have to work out what settings are needed to enable it (default or not?) - but when running in a terminal it would be good if the copy (at least) had some sort of progress meter given we expect these operations to be lengthy.

Would need to decide what metrics go on the meter and also the tech to do the meter.

It 100% needs to be able to be switched off as there are clear circumstances were we do not want any progress output (just summary stats at the end)

Yeah agree, most popular library seems to be: https://crates.io/crates/indicatif

I think copy should have progress bar with total size and transfer rate?

The generate command can also have some progress bars as the total size of the file is usually known.

Yep sounds good - no rush on this (unless it happens to be a fun diversion) - as our first use cases for the copier will be inside steps s3 copy where we won't need a progress bar
