Struct WriteSerialGuard 

pub struct WriteSerialGuard { /* private fields */ }

RAII guard on the in-process write-serialization gate.

Owns a clone of the env’s Arc<AtomicBool> so it is Send + 'static (it does NOT borrow the env). Constructed only by the crate-internal gate acquire, which sets the flag to true via a CAS; Drop clears it with a Release store so a writer that releases on one thread is observed by an acquirer that CASes on another.

At most one WriteSerialGuard exists per env at a time — that is the single-writer invariant the CAS enforces.

Trait Implementations

impl Debug for WriteSerialGuard

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

Formats the value using the given formatter.

impl Drop for WriteSerialGuard

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.
