System power operations.

Required Methods

fn get_system_power_state<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = SystemPowerState> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns the current system power state.

fn system_powerctl(&self, cmd: u32) -> Result<(), Status>

Executes a system power control command (e.g. reboot, shutdown).

fn has_resources(&self) -> bool

Returns true if the necessary power resource is available.

fn exit(&self, status: i32)

Exits the process.

Dyn Compatibility

This trait is dyn compatible.

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