README
MCache library
go-mcache - this is a fast key:value storage. Its major advantage is that, being essentially a thread-safe .
map[string]interface{}
with expiration times, it doesn't need to serialize, and quick removal of expired keys.
Installation
~ $ go get -u github.com/OrlovEvgeny/go-mcache
Example a Pointer value (vary fast method)
type User struct {
Name string
Age uint
Bio string
}
func main() {
//Start mcache instance
MCache = mcache.New()
//Create custom key
key := "custom_key1"
//Create example struct
user := &User{
Name: "John",
Age: 20,
Bio: "gopher 80 lvl",
}
//args - key, &value, ttl (or you need never delete, set ttl is mcache.TTL_FOREVER)
err := MCache.Set(key, user, time.Minute*20)
if err != nil {
log.Fatal(err)
}
if data, ok := MCache.Get(key); ok {
objUser:= data.(*User)
fmt.Printf("User name: %s, Age: %d, Bio: %s\n", objUser.Name, objUser.Age, objUser.Bio)
}
}

What should be done
- [x] the possibility of closing
- [x] r/w benchmark statistics
- [ ] rejection of channels in safeMap in favor of sync.Mutex (there is an opinion that it will be faster)
