Trait Manager 

pub trait Manager {
    // Required methods
    fn reload(&mut self) -> Result<(), CallError>;
    fn reset_failed(&mut self, unit: &str) -> Result<(), CallError>;
    fn start(&mut self, unit: &str) -> Result<(), CallError>;
    fn stop(&mut self, unit: &str) -> Result<(), CallError>;
    fn active_state(&mut self, unit: &str) -> Result<Option<String>, CallError>;
}

What the manager is asked to do, so a control can record it instead of reaching a manager.

Required Methods

fn reload(&mut self) -> Result<(), CallError>

Reloads the unit files.

fn reset_failed(&mut self, unit: &str) -> Result<(), CallError>

Clears a unit’s failed state and start-rate counter.

fn start(&mut self, unit: &str) -> Result<(), CallError>

Starts a unit.

fn stop(&mut self, unit: &str) -> Result<(), CallError>

Stops a unit.

fn active_state(&mut self, unit: &str) -> Result<Option<String>, CallError>

The unit’s state as the manager reports it (active, deactivating, inactive, failed), or nothing when the manager holds no such unit.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
