ficklepickle

ficklepickle

it's a simple struct pickling library with compression and encryption

read/write/delete available over file, db and tcp server

• sample usage; sample rpc server

|

Usage

• to fetch this go package go get -u github.com/abhishekkr/ficklepickle

• import required to use import "github.com/abhishekkr/ficklepickle"

• say we have a structure

type Metric struct {
  Name string
  Percent int
}

xload = Metric{Name: "somework", Percent: 25}
yload := Metric{}

In memory

• Pickle

pickle, err := ficklepickle.Pickle(xload)
if err != nil {
  panic("Pickle error for Metric")
}
// pickled data is 'pickle' as byte array

• UnPickle

if err := ficklepickle.Unpickle(pickle, &yload); err != nil {
  panic("Unpickle error for Metric")
}
fmt.Println(yload.Name) // shall output 'somework'

Persist using a mode (local file, database; remote TCP service)

// for normal local file
mode = ficklepickle.RwFile

// for github.com/abhishekkr/gol/golkeyval supported database
mode = ficklepickle.RwDb // database type default: leveldb, configurable

// for remote TCP server hosted pickles, can be used to share across services
// sample TCP service can be created similar to example code at: _tests_behavioral_/fickle_server.go
mode = ficklepickle.RwRpc // remote database type default: leveldb, configurable in Rpc Server

• Pickle

err := ficklepickle.Write(mode, "metric_xload", xload)
if err != nil {
  panic("Pickle error for Metric")
}

• UnPickle

if err := ficklepickle.Read(mode, "metric_xload", &yload); err != nil {
  panic("Unpickle error for Metric")
}
fmt.Println(yload.Name) // shall output 'somework'

• Delete Pickle

if err := ficklepickle.Delete(mode, "metric_xload"); err != nil {
  panic("Delete pickle error for Metric")
}
