Struct FileLock 

Source
pub struct FileLock {
    pub recovered_stale: Option<LockOwner>,
    /* private fields */
}
Expand description

Held until dropped (or the process dies).

Fields§

§recovered_stale: Option<LockOwner>

Owner of a lock left behind by a process that is gone, when one was found.

Implementations§

Source§

impl FileLock

Source

pub fn acquire(path: &Path, options: &LockOptions) -> Result<Self>

Exclusive lock; waits up to options.timeout.

Source

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

Fail immediately when busy.

Source

pub fn acquire_shared(path: &Path, options: &LockOptions) -> Result<Self>

Shared (reader) lock: many readers, excluded by a writer. No owner record.

Source

pub fn path(&self) -> &Path

Source

pub fn current_owner(lock_path: &Path) -> Option<LockOwner>

The holder recorded on disk for lock_path (diagnostics; may be stale).
