pub struct OwnerInfo {
pub session: String,
pub pid: u32,
pub host: String,
pub cwd: String,
pub started: u64,
}Expand description
Provenance of a live alive-lock holder, persisted inside the lock file.
Written by acquire right after the exclusive flock is taken; read
back with read_owner_info. The lock file doubles as the storage so
there is exactly one artifact per session — the existing orphan reaper
(reap_orphans) and the RAII unlink in AliveGuard::drop clean it
up with no extra bookkeeping.
Fields§
§session: StringOwning session id (same as the lock-file name).
pid: u32OS pid of the holder.
host: StringHostname of the holder (empty when gethostname fails).
cwd: StringWorking directory at acquisition time.
started: u64Unix seconds at acquisition time.
