Struct WriterLock 

pub struct WriterLock { /* private fields */ }

RAII guard for a held WRITER_LOCK byte. Dropping the guard releases the OS-side lock. The guard is !Send only by virtue of the file handle it does NOT own — the underlying lock is per-fd, so as long as the fd survives, releasing from any thread is sound.

Implementations

impl WriterLock

pub fn release(self) -> Result<()>

Explicitly release the lock. Equivalent to Drop but lets the caller observe a release error (the Drop impl silently swallows errors because panics from Drop are toxic).

Errors

Returns Error::Io on the unlikely event that the OS rejects the unlock syscall.

Trait Implementations

impl Debug for WriterLock

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

Formats the value using the given formatter.

impl Drop for WriterLock

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.
