Store - Read and write data structures
Store provides the ability to write the data structures to a file and read from a file in the Go programming language.
The module provides possibility of the data structures in a JSON format or in a binary format. During the writing or reading process the file is locked.
Reading/writing in JSON format were implemented with the standard library encoding/json.
For reading/writing in binary format the module is encoding/gob used.
Usage
Writing in JSON format to a file:
type message struct {
Name string
Timestamp time.Time
Payload []byte
Ssid []uint32
}
msg := &message{
Name: "John",
Timestamp: time.Now(),
Payload: []byte("hi"),
Ssid: []uint32{1, 2, 3},
}
if err := WriteJSON("./temp.json", msg); err != nil {
log.Fatalln(err)
}
Read from a file written in JSON format:
var msg message
if err := ReadJSON("./temp.json", &msg); err != nil {
log.Fatalln(err)
}
fmt.Println(msg.Name) // Output John
Writing in binary format to a file:
type message struct {
Name string
Timestamp time.Time
Payload []byte
Ssid []uint32
}
msg := &message{
Name: "John",
Timestamp: time.Now(),
Payload: []byte("hi"),
Ssid: []uint32{1, 2, 3},
}
if err := WriteBinary("./temp.bin", msg); err != nil {
log.Fatalln(err)
}
Read from a file written in binary format:
var msg message
if err := ReadBinary("./temp.bin", &msg); err != nil {
log.Fatalln(err)
}
fmt.Println(msg.Name) // Output John
