pub fn id(&self) -> ProcessId

Returns the id of the process.

pub fn executable(&self) -> Result<FilePath, ProcessExecutablePathError>

Returns the executable path of the Process.

pub fn send_signal(&self, signal: Signal) -> Result<(), ProcessSendSignalError>

Sends a signal to the process.

pub fn get_priority(&self) -> Result<u8, ProcessGetSchedulerError>

pub fn set_priority( &mut self, priority: u8, ) -> Result<(), ProcessGetSchedulerError>

Set the priority of the process. 0 is the lowest priority and 255 the highest.

pub fn get_scheduler(&self) -> Result<Scheduler, ProcessGetSchedulerError>
