Implementations§

Source§

impl DaemonManager

Source

pub fn New(PidFilePath: Option<PathBuf>) -> Result<Self>

Create a new DaemonManager instance

Source

pub async fn AcquireLock(&self) -> Result<()>

Acquire daemon lock to ensure single instance This method provides comprehensive defensive coding with:

  • Race condition protection through mutex locking
