# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
Simple wrappers for primitive types to enforce atomic access.
## Installation
`go get -u go.uber.org/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.
```go
var atom atomic.Uint32
atom.Store(42)
atom.Sub(2)
atom.CAS(40, 11)
```
See the [documentation][doc] for a complete API specification.
## Development Status
Stable.
