• ConcurrentMap - Implements the generic async.Map interface in a thread-safe manner by delegating load/store operations to the underlying sync.Map.
• ShardedMap - Implements the generic async.Map interface in a thread-safe manner, delegating load/store operations to one of the underlying async.SynchronizedMaps (shards), using a key hash to calculate the shard number.
• Future - A placeholder object for a value that may not yet exist.
• Promise - While futures are defined as a type of read-only placeholder object created for a result which doesn’t yet exist, a promise can be thought of as a writable, single-assignment container, which completes a future.
• Task - A data type for controlling possibly lazy and asynchronous computations.
• Once - An object similar to sync.Once having the Do method taking f func() (T, error) and returning (T, error).
• Value - An object similar to atomic.Value, but without the consistent type constraint.
• WaitGroupContext - A WaitGroup with the context.Context support for graceful unblocking.
• ReentrantLock - A mutex that allows goroutines to enter into the lock on a resource more than once.
• PriorityLock - A non-reentrant mutex that allows for the specification of lock acquisition priority.
