openssh-sftp-client 0.12.2

//! openssh sftp client, implements [sftp v3] accodring to
//! [`openssh-portable/sftp-client.c`] and provides
//! an easy-to-use highlevel API.
//!
//! All `async` functions in this module are cancel safe.
//!
//! Internally, this is archived by first writing requests into a write buffer
//! containing [`bytes::Bytes`] and then flush all buffers at once periodically
//! to archive cancel safety and improve efficiencies.
//!
//! However, cancelling the future does not actually has any effect,
//! since the requests are sent regardless of the cancellation.
//!
//! Thus, if you cancel a future that changes the remote filesystem in any way,
//! then the change would still happen regardless.
//!
//! ## Usage
//!
//! It is recommended that you use this crate with [openssh].
//!
//! You can also use this crate directly by using whatever ssh library
//! to launch the `sftp` subsystem, then pass the stdin/stdout to
//! [`Sftp::new`].
//!
//! ## Extensions
//!
//! This crate support the following extensions:
//!  - limits
//!  - expand path
//!  - fsync
//!  - hardlink
//!  - posix rename
