Am I missig somthing?

Are there are any higher level rsync libraries, could be a wrapper of this library or another library.
I'm hoping for an api where I specify ssh keys, username and address to open a session and then specify a path to sync between the local and remote machines.
Unfortunately everything I've seen so far is either purely a CLI application or provides the same level of abstraction as librsync or fast_rsync.

If no such library exists feel free to just close this issue, thanks.

It's not obvious how to choose good parameters for SignatureOptions. The docs do nicely explain what kind of effect the parameters have, but they don't make it easy to choose concrete values.

It might be good to

• impl Default for SignatureOptions, if universally reasonable defaults exist, or
• add a constructor that produces parameters that are good for e.g. a given file size and acceptable collision rate, or
• elaborate the documentation.

I've two questions:

• Does this library support streaming API? Example: need to calculate deltas for large files (4GB+). From the examples I found all the delta, and signatures are memory vectors
• Is this library compatible with the original librsync in C++?

In general would be great having more usage examples in this repo. Thanks!

I developed a small linux server backup application in flutter/dart that runs on a local windows machine, this application backs up servers via SSH/SFTP, but currently it only does full backups, it doesn't do incremental backups and it's quite slow, I I want to port this application to rust, using the lib "iron-carrier" makes the synchronization of a directory on a linux server to a windows machine?
