Hash on the fly with rclone?

I think the not quite merged yet hasher backend would help with this. Its job is to cache hashes so they don't get re-computed unecessarily.

I really appreciate this response. BY the way, this is not really my request. This idea was proposed years ago:

@thestigma mentioned this at When does rclone compute a file hash? - #2 by thestigma

Any time you already have to read the entire file anyway though - calculating the hash can be done almost for free (such as for the upload of a file). The only extra cost is a fairly trivial amount of CPU, so I think rclone generally tends to do this to verify a successful transfer.

… but I didn't see any followups on this matter.

I have also asked about this for ref: https://www.reddit.com/r/rclone/comments/qbgd9x/hash_on_the_fly_with_rclone/
