# atomic [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov] [![Go Report Card][reportcard-img]][reportcard]

Simple wrappers for primitive types to enforce atomic access.

## Installation

```shell
$ go get -u go.uber.org/atomic@v1
```

Note: If you are using Go modules, this package will fail to compile with the
import path `github.com/uber-go/atomic`. To continue using that import path,
you will have to add a `replace` directive to your `go.mod`, replacing
`github.com/uber-go/atomic` with `go.uber.org/atomic`.

```shell
$ go mod edit -replace github.com/uber-go/atomic=go.uber.org/atomic@v1
```

## 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.
