fn write(&self, current_task: &CurrentTask, data: Vec<u8>) -> Result<(), Errno>

Writing a string activates a “wakeup source” preventing the system from entering a low-power state.

1. Simple string (no whitespace): Activates or creates a wakeup source with that name.
2. String with whitespace: The first part (before the whitespace) is the wakeup source name. The second part is a timeout in nanoseconds, after which the wakeup source is automatically deactivated.

fn read(&self, current_task: &CurrentTask) -> Result<Cow<'_, [u8]>, Errno>

fn write_locked( &self, _locked: &mut Locked<FileOpsCore>, current_task: &CurrentTask, data: Vec<u8>, ) -> Result<(), Errno>

fn read_locked( &self, _locked: &mut Locked<FileOpsCore>, current_task: &CurrentTask, ) -> Result<Cow<'_, [u8]>, Errno>

fn open( &self, _locked: &mut Locked<FileOpsCore>, _file: &FileObject, _current_task: &CurrentTask, ) -> Result<(), Errno>
