Struct DaemonLock 

pub struct DaemonLock { /* private fields */ }

RAII guard that holds the daemon PID lock file.

Why: tie the lock file’s lifetime to the daemon process lifetime so the file is removed on both clean shutdown and panic, without requiring every exit path to call an explicit cleanup function. The guard is not Clone or Send — it is constructed once in main and lives for the full daemon lifetime. What: wraps the path of the written lock file. Drop removes it best-effort (I/O errors are silently swallowed — the file will be reclaimed as stale by the next invocation anyway). Test: daemon_lock_drops_removes_file.

Trait Implementations

impl Debug for DaemonLock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for DaemonLock

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
