Trait tor_persist::state_dir::ContainsInstanceStateGuard

pub trait ContainsInstanceStateGuard {
    // Required method
    fn raw_lock_guard(&self) -> Arc<LockFileGuard>;
}

Available on crate feature state-dir only.

Objects that co-own a lock on an instance

Each type implementing this trait mutually excludes independently-acquired InstanceStateHandles, and anything derived from them (including, therefore, ContainsInstanceStateGuard implementors with independent provenance.)

Required Methods

fn raw_lock_guard(&self) -> Arc<LockFileGuard>

Obtain a raw clone of the underlying filesystem lock

This lock (and clones of it) will mutually exclude re-acquisition of the same instance.
