|

## [1.11.0] - 2023-05-02
|
||||
### Fixed
|
||||
- Fix initialization of `Value` wrappers.
|
||||
|
||||
### Added
|
||||
- Add `String` method to `atomic.Pointer[T]` type allowing users to safely print
|
||||
underlying values of pointers.
|
||||
|
||||
[1.11.0]: https://github.com/uber-go/atomic/compare/v1.10.0...v1.11.0
|
||||
|
||||
## [1.10.0] - 2022-08-11
|
||||
### Added
|
||||
- Add `atomic.Float32` type for atomic operations on `float32`.
|
||||
- Add `CompareAndSwap` and `Swap` methods to `atomic.String`, `atomic.Error`,
|
||||
and `atomic.Value`.
|
||||
- Add generic `atomic.Pointer[T]` type for atomic operations on pointers of any
|
||||
type. This is present only for Go 1.18 or higher, and is a drop-in for
|
||||
replacement for the standard library's `sync/atomic.Pointer` type.
|
||||
|
||||
### Changed
|
||||
- Deprecate `CAS` methods on all types in favor of corresponding
|
||||
`CompareAndSwap` methods.
|
||||
|
||||
Thanks to @eNV25 and @icpd for their contributions to this release.

||||
|
||||

|
||||
### Added

||||
- Add `Float64.Swap` to match int atomic operations.
|
||||

|
||||
### Added

|
||||

|
||||
|
||||
[1.8.0]: https://github.com/uber-go/atomic/compare/v1.7.0...v1.8.0
|
||||
|
||||
## [1.7.0] - 2020-09-14

|
||||
|

||||
|
||||
### Removed

|
||||
|
||||
[1.7.0]: https://github.com/uber-go/atomic/compare/v1.6.0...v1.7.0

||||
## [1.5.1] - 2019-11-19
|
||||
- Fix bug where `Bool.CAS` and `Bool.Toggle` do work correctly together
|
||||
causing `CAS` to fail even though the old value matches.

||||
|
||||

|
||||
your `go.mod`.

# 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.
|
||||
|
||||
## Development Status
|
||||
|
||||
Stable.
