Struct StoreLock 

pub struct StoreLock { /* private fields */ }

Cross-process advisory lock held through an open file handle.

Lock files persist after release. Unlinking an advisory lock file can split contenders across the unlinked inode and a newly-created inode, allowing two processes to both believe they hold the same lock. Only [Store::sweep_stale_key_locks] unlinks one, and only while holding it; every acquisition then checks that the path still names the file it locked, and starts over when it does not.

Implementations

impl StoreLock

pub fn try_acquire(path: &Path) -> Result<Option<Self>>

Trait Implementations

impl Drop for StoreLock

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.
