    // Required methods
    fn lock(&self);
    fn unlock(&self);
}

Serializes queue access with another API that shares the same queue.

A queue must be externally synchronized. When a native decoder submits to the same queue as the renderer, both sides have to take one lock, and neither owns the other’s submissions. GpuContext takes it around every call that can reach the native queue, not only submissions. Implementations must be re-entrant: one thread can submit while already holding the lock, for example when a queue-completion callback releases a resource.

Required Methods

fn lock(&self)

Acquires exclusive access to the shared queue.

fn unlock(&self)

Releases access taken by ExternalQueueLock::lock.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
