yazi-sftp

A fork of russh-sftp used by Yazi, with some changes:

• Supports paths containing invalid UTF-8
• Supports retrieving file nlink, username, and group
• Uses generic return parameters for a more idiomatic API, e.g.:

  let attrs: responses::Attrs = session.send(requests::Stat::new(path)).await?
  

• Reduced dependencies
• Performance optimizations:
  • Copy-on-write for all packets to avoid unnecessary memory allocation
  • Packet lengths are precomputed to avoid secondary allocations
  • Avoids cloning buffers in AsyncRead and AsyncWrite implementations
