Russh SFTP

SFTP subsystem supported server and client for Russh and more!

Crate can provide compatibility with anything that can provide the raw data stream in and out of the subsystem channel.
Implemented according to version 3 specifications (most popular).

The main idea of the project is to provide an implementation for interacting with the protocol at any level.

Median throughput over six runs against OpenSSH in Docker (tmpfs), using the same 128 MiB payload and transfer settings: AES-128-GCM, 16 concurrent requests and TCP_NODELAY=true. Connection setup is excluded. Uploads wait for acknowledgements and close.

TCP_NODELAY disables Nagle's algorithm, reducing delays for small SFTP requests. Enable it with russh::client::Config { nodelay: true, ..Default::default() }. Go enables it by default.
