Struct tokio::sync::lock::LockGuard

source · [−]

pub struct LockGuard<T>(_);

Expand description

A handle to a held Lock.

As long as you have this guard, you have exclusive access to the underlying T. The guard internally keeps a reference-couned pointer to the original Lock, so even if the lock goes away, the guard remains valid.

The lock is automatically released whenever the guard is dropped, at which point poll_lock will succeed yet again.
