Struct DistributedLock 

pub struct DistributedLock {
    pub name: &'static str,
    pub ttl_ms: u64,
}

const-constructible named lock. The backend comes from DI (Arc<dyn DLockBackend>), so the same static works across environments.

Fields

name: &'static str

ttl_ms: u64

Implementations

impl DistributedLock

pub const fn new(name: &'static str, ttl_ms: u64) -> Self

pub async fn try_lock( &self, backend: &Arc<dyn DLockBackend>, ) -> Option<LockGuard>

Non-blocking acquisition. Ok(None) = another holder exists (or the backend is down — conservative). On success the guard auto-renews every ttl/3 until dropped.
