Synchronization and asynchronous computation package for Go


Async provides synchronization and asynchronous computation utilities for Go.

The implemented patterns were taken from Scala and Java.

Overview

  • 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.
  • Reentrant Lock - Mutex that allows goroutines to enter into the lock on a resource more than once.
  • Optimistic Lock - Mutex that allows optimistic reading. Could be retried or switched to RLock in case of failure. Significantly improves performance in case of frequent reads and short writes. See benchmarks.
