LockGuard

Struct LockGuard 

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

Owned proof that the holder currently has exclusive access to a key.

Drop semantics: when a LockGuard is dropped without an explicit DistributedLock::release call, a tracing::warn! records the leak. The lock will still expire by TTL, so correctness is preserved, but the warning surfaces forgotten release calls in telemetry.

Implementations§

Source§

impl LockGuard

Source

pub fn new(key: AdvisoryKey) -> Self

Construct a guard. Backend DistributedLock impls call this after a successful acquire — the token is the per-acquire ownership marker the backend stores alongside the lock value.

Source

pub const fn key(&self) -> &AdvisoryKey

Borrow the lock key.

Source

pub fn token(&self) -> &str

Borrow the per-acquire ownership token.

Source

pub fn held_for(&self) -> Duration

Wall-clock duration the guard has been held.

Source

pub fn mark_released(&mut self)

Mark the guard as released — backend DistributedLock impls call this from release() so the Drop impl does not warn. Outside backend code there is no reason to call this directly.
