go-syncutils

go-lock is a Golang library implementing some missing synchronization primitives in golang standart library:

mutex

• Mutex and RWMutex with timeout mechanism (with Trylock and Lock with timeout)
• PMutex is promote (RWMutex with promote from read lock to read write lock) with timeout mechanism (with Trylock and Lock with timeout)
• ChanMutex is a simple mutex with channel

atomic

Simple wrappers for primitive types to enforce atomic access (based on https://github.com/uber-go/atomic).

Usage

The standard library's sync/atomic is powerful, but it's easy to forget which variables must be accessed atomically. go.uber.org/atomic preserves all the functionality of the standard library, but wraps the primitive types to provide a safer, more convenient API.

var atom atomic.Uint32
atom.Store(42)
atom.Sub(2)
atom.CompareAndSwap(40, 11)
