Crate rash 

rash — Rust Auto SSH.

Starts an ssh session or tunnel, monitors it, and restarts it if it dies or stops passing traffic. A behaviour-compatible reimplementation of autossh(1) by Carson Harding.

The library exists so the pieces that are pure — argument splitting, config resolution, the exit-status policy, the backoff curve — can be tested without spawning anything.

Modules

backoff

Restart backoff — a port of autossh’s grace_time() (autossh.c:1115-1154).

cli

Splitting argv into rash’s own options and ssh’s.

config

Resolving a complete configuration from the command line and the environment.

daemon

Detaching from the terminal, for -f.

log

Log sinks: syslog, a file, or stderr.

monitor

Testing that the tunnel still carries traffic.

pidfile

The pid file, removed when the guard is dropped.

settings

The optional TOML configuration file.

supervise

The supervision loop.

Macros

log_debug
