Struct FileLock 

pub struct FileLock { /* private fields */ }

File-level lock for .aplan files. Creates a .aplan.lock sidecar that prevents concurrent writes to the same planning file.

The lock is held for the duration of the write and released on drop.

Implementations

impl FileLock

pub fn acquire(aplan_path: &Path) -> Result<Self, LockError>

Acquire a file-level lock for the given .aplan path.

Creates a .aplan.lock sidecar file containing the current PID. Retries with backoff up to FILE_LOCK_TIMEOUT. Stale locks from dead processes are automatically recovered.

pub fn path(&self) -> &Path

Path to the lock file.

Trait Implementations

impl Drop for FileLock

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.
