Struct QuiescenceGuard 

pub struct QuiescenceGuard { /* private fields */ }

Fresh non-spawning exclusive custody over an exact existing regular sidecar.

Drop explicitly unlocks, including transient duplicated/inherited copies of this guard. Unlike command custody, this guard cannot intentionally dispatch.

Implementations

impl QuiescenceGuard

pub fn acquire( path: &Path, expected: FileIdentity, ) -> Result<Self, CustodyError>

Admit the retained identity before locking, then recheck the opened descriptor.

Missing sidecars are never created. A different regular inode rejects before lock contention can obscure replacement. Special entries use Host FS admission.

Errors

Returns active custody, replacement, missing/unsafe entries or native I/O errors.

pub const fn identity(&self) -> FileIdentity

Read the exact admitted identity.

Trait Implementations

impl Debug for QuiescenceGuard

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

Formats the value using the given formatter.

impl Drop for QuiescenceGuard

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.
