Struct ArcRwLockAccess 

pub struct ArcRwLockAccess<T> { /* private fields */ }

Lock access implementation for Arc<RwLock>

RwLock Semantics

RwLock provides reader-writer lock semantics:

• Multiple readers can access simultaneously (shared/immutable access)
• Only one writer can access at a time (exclusive/mutable access)
• Readers and writers are mutually exclusive

Cloning Behavior

Like ArcMutexAccess, this struct only contains PhantomData<T>. Cloning is a zero-cost operation - no data is copied.

Performance vs Mutex

• Better for read-heavy workloads: Multiple concurrent readers
• Slightly more overhead: RwLock has more complex internal state
• Use when: Many readers, few writers
• Avoid when: Frequent writes or simple cases (use Mutex)
