Async is a synchronization and asynchronous computation package for Go.
- ConcurrentMap - Implements the generic
async.Mapinterface in a thread-safe manner by delegating load/store operations to the underlyingsync.Map. - ShardedMap - Implements the generic
async.Mapinterface in a thread-safe manner, delegating load/store operations to one of the underlyingasync.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.
- Executor - A worker pool for executing asynchronous tasks, where each submission returns a Future instance representing the result of the task.
- 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.Contextsupport 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.
