Expand description

Uniform interface that all subsystems must implement

This trait provides a consistent lifecycle and monitoring interface for all subsystems managed by the Database.

Required Methods§

Source

fn name(&self) -> &'static str

Get the unique name of this subsystem

Source

fn start(&mut self) -> Result<()>

Start the subsystem

This method should initialize the subsystem and start any background threads or processes. It should be idempotent - calling start() on an already running subsystem should succeed without side effects.

Source

fn shutdown(&mut self) -> Result<()>

Shutdown the subsystem

This method should gracefully shut down the subsystem and clean up any resources. This is a terminal operation - once shutdown, the subsystem cannot be restarted. It should be idempotent - calling shutdown() on an already shutdown subsystem should succeed without side effects.
