Struct StoreLock

pub struct StoreLock { /* private fields */ }

Holds the exclusive data-folder lock until dropped.

Drop explicitly unlocks before closing the file. Closing alone may retain the lock while a helper process briefly holds an inherited descriptor.

Implementations

impl StoreLock

pub fn acquire(data_dir: &Path) -> Result<Self>

Waits for another Aède operation to finish, then locks this data folder.

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

Fails with io::ErrorKind::WouldBlock if another operation owns it.

Trait Implementations
