LockGuard

Struct LockGuard 

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

RAII guard for distributed locks

Automatically releases the lock when dropped. Contains metadata about the lock for verification and monitoring purposes.

Implementations§

Source§

impl LockGuard

Source

pub fn new( resource: String, token: LockToken, acquired_at: DateTime<Utc>, ttl: Duration, backend: Arc<dyn DistributedLock>, ) -> Self

Create a new lock guard

Source

pub fn resource(&self) -> &str

Get the locked resource name

Source

pub fn token(&self) -> &LockToken

Get the lock token

Source

pub fn acquired_at(&self) -> DateTime<Utc>

Get the acquisition timestamp

Source

pub fn ttl(&self) -> Duration

Get the lock TTL

Source

pub fn is_expired(&self) -> bool

Check if the lock has expired (based on TTL)

Source

pub fn time_remaining(&self) -> Duration

Get time remaining before expiration

Source

pub async fn release(self) -> StateResult<()>

Manually release the lock early

This consumes the guard and releases the lock. Normally not needed as the lock is released automatically on drop.
