Struct ExclusiveFence 

pub struct ExclusiveFence { /* private fields */ }

The exclusive side of the maintenance fence for one database file.

Acquiring it waits for outstanding OperationGuards to drain (bounded by deadline); holding it makes every subsequent guarded operation fail typed. The Phase 6 migration machinery composes one of these per database file it intends to touch, across both candidate roots.

Implementations

impl ExclusiveFence

pub fn try_acquire(db_path: &Path) -> Result<Option<Self>, SqliteStoreError>

Try to take the fence without waiting.

pub fn acquire( db_path: &Path, deadline: Duration, ) -> Result<Self, SqliteStoreError>

Take the fence, waiting up to deadline for in-flight operations to drain.

pub fn lock_path(&self) -> &Path

The lock file this fence holds.

Trait Implementations

impl Debug for ExclusiveFence

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

Formats the value using the given formatter.

impl Drop for ExclusiveFence

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.
