# 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
|
||
|
|
```
|
||
|
|
|
||
|
|
### Legacy Import Path
|
||
|
|
|
||
|
|
As of v1.5.0, the import path `go.uber.org/atomic` is the only supported way
|
||
|
|
of using this package. If you are using Go modules, this package will fail to
|
||
|
|
compile with the legacy import path path `github.com/uber-go/atomic`.
|
||
|
|
|
||
|
|
We recommend migrating your code to the new import path but if you're unable
|
||
|
|
to do so, or if your dependencies are still using the old import path, you
|
||
|
|
will have to add a `replace` directive to your `go.mod` file downgrading the
|
||
|
|
legacy import path to an older version.
|
||
|
|
|
||
|
|
```
|
||
|
|
replace github.com/uber-go/atomic => github.com/uber-go/atomic v1.4.0
|
||
|
|
```
|
||
|
|
|
||
|
|
You can do so automatically by running the following command.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ go mod edit -replace github.com/uber-go/atomic=github.com/uber-go/atomic@v1.4.0
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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.
|
||
|

|

|
