ABool 💡
Atomic Boolean library for Golang, optimized for performance yet simple to use.
Use this for cleaner code.
Usage
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
cond.SetToIf(false, true) // Set to true if it is false, returns false(not set)
// embedding
type Foo struct {
cond *abool.AtomicBool // always use pointer to avoid copy
}
Benchmark:
- Golang 1.6.2
- OS X 10.11.4
