Quick Start
package main
import (
"bytes"
"log"
"github.com/aos-dev/go-storage/v3/pairs"
"github.com/aos-dev/go-service-fs/v2"
)
func main() {
// Init a service.
store, err := fs.NewStorager(pairs.WithWorkDir("/tmp"))
if err != nil {
log.Fatalf("service init failed: %v", err)
}
content := []byte("Hello, world!")
length := int64(len(content))
r := bytes.NewReader(content)
_, err = store.Write("hello", r, length)
if err != nil {
log.Fatalf("write failed: %v", err)
}
var buf bytes.Buffer
_, err = store.Read("hello", &buf)
if err != nil {
log.Fatalf("storager read: %v", err)
}
log.Printf("%s", buf.String())
}
