Graceful process restarts in Rust.
This crate facilitates upgrading or reconfiguring a service without disrupting existing connections. This is achieved by forking the process and communicating a small amount of state between the old and new processes; once the new process has started successfully the old process may terminate.
This crate has the following goals:
Inspired by the tableflip go package but not a direct replacement.
A full example is given in the restarter example service.
The main struct of interest is RestartConfig
which has methods for detecting or initiating
restart. For shutting down a restarted process, the ShutdownCoordinator
provides the means for
both signalling a shutdown event to spawned tasks, and awaiting their completion.
