A Go library to find diff slice of struct (when feed new data then output show id was added , id was updated or id was deleted)
package main
import (
"fmt"
diff "github.com/panapol-p/go-slice-struct-diff"
)
type FeedData struct {
ID string `diff:"id"`
Name string
Score float32
}
func main() {
fs := []FeedData{
{ID: "1", Name: "Bob", Score: 98.50},
{ID: "2", Name: "Joe", Score: 92.50},
}
d := diff.NewDiff[FeedData]()
// set callback func if you need
f := func(e []diff.Events[FeedData]) {
fmt.Println("[callback func]", "receive new event!!", e)
}
d.SetCallback(f)
events := d.AddNewValue(fs)
fmt.Println(events) // [{1 added {1 Bob 98.5}} {2 added {2 Joe 92.5}}]
fs = []FeedData{
{ID: "1", Name: "Bob", Score: 96.50},
{ID: "2", Name: "Joe", Score: 92.50},
{ID: "3", Name: "Micky", Score: 89.70},
}
events = d.AddNewValue(fs)
fmt.Println(events) // [{1 updated {1 Bob 96.5}} {3 added {3 Micky 89.7}}]
fs = []FeedData{
{ID: "1", Name: "Bob", Score: 96.50},
}
events = d.AddNewValue(fs)
fmt.Println(events) // [{2 deleted { 0}} {3 deleted { 0}}]
