memkv
Simple in memory k/v store.
Usage
package main
import (
"fmt"
"log"
"github.com/kelseyhightower/memkv"
)
func main() {
s := memkv.New()
s.Set("/myapp/database/username", "admin")
s.Set("/myapp/database/password", "123456789")
s.Set("/myapp/port", "80")
kv, err := s.Get("/myapp/database/username")
if err != nil {
log.Fatal(err)
}
fmt.Printf("Key: %s, Value: %s\n", kv.Key, kv.Value)
ks, err := s.GetAll("/myapp/*/*")
if err == nil {
for _, kv := range ks {
fmt.Printf("Key: %s, Value: %s\n", kv.Key, kv.Value)
}
}
}
Key: /myapp/database/username, Value: admin
Key: /myapp/database/password, Value: 123456789
Key: /myapp/database/username, Value: admin

Types ¶
type Store ¶
type Store struct {
FuncMap map[string]interface{}
sync.RWMutex
// contains filtered or unexported fields
}
A Store represents an in-memory key-value store safe for concurrent access.
func (Store) Get ¶
Get gets the KVPair associated with key. If there is no KVPair associated with key, Get returns KVPair{}, ErrNotExist.
func (Store) GetAll ¶
GetAll returns a KVPair for all nodes with keys matching pattern. The syntax of patterns is the same as in path.Match.
