CommandQuiescenceGuard

ic_backup::ops::persistence

Struct CommandQuiescenceGuard 

Source 
pub struct CommandQuiescenceGuard { /* private fields */ }
Expand description

Fresh exclusive quiescence bound to Backup’s retained original journal record.

Host owns descriptor exclusion and explicit unlock on drop. This guard cannot spawn; terminal settlement and reference-release admission remain separate.

Implementations§

Source§

impl CommandQuiescenceGuard

Source

pub fn acquire( expected: &CommandCustodyRecord, ) -> Result<Self, CommandLifetimeLockError>

§Errors

Rejects active holders, replaced/missing/unsafe sidecars and I/O failures.

Source

pub fn record(&self) -> &CommandCustodyRecord

Read the exact retained evidence freshly admitted by this guard.
