|
:bulb: Atomic boolean library for Golang, optimized for performance yet simple to use.
|
|
|
|
## Usage
|
|
|
|
```go
|
|
import "github.com/tevino/abool"
|
|
|
|
cond := abool.New() // default to false
|
|
|
|
cond.Set() // set to true
|
|
cond.IsSet() // returns true
|
|
cond.UnSet() // set to false
|
|
cond.SetTo(true) // set to whatever you want
|
|
|
|
|
|
// embedding
|
|
type Foo struct {
|
|
cond *abool.AtomicBool // always use pointer to avoid copy
|
|
}
|
|
```
|
