Struct SessionLock 

pub struct SessionLock { /* private fields */ }

RAII guard for the add/remove advisory lock.

Acquired with SessionLock::acquire; the lock file is removed when the guard drops. Hold it for the entire mutate-the-session critical section of cmd_add / cmd_remove.

Implementations

impl SessionLock

pub fn acquire(repo_root: &Path) -> Result<Self, PawError>

Attempts to acquire the advisory lock for repo_root.

Creates <repo>/.git-paw/ if needed, then atomically creates the lock file. Returns PawError::SessionError with an actionable “operation in progress” message when the lock is already held (the file already exists) — the second concurrent add/remove SHALL see this rather than proceed.

Trait Implementations

impl Debug for SessionLock

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

Formats the value using the given formatter.

impl Drop for SessionLock

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.
