Function ExampleAppendMap

msgp/iter_test.go:280–298

Example: appending a map to a byte slice using AppendMap (non-sorted). Uses a single-entry map to keep output deterministic. Use AppendMapSorted to write a sorted map.

// Uses a single-entry map to keep output deterministic.
// Use AppendMapSorted to write a sorted map.
func ExampleAppendMap() {
	var b []byte

	// Append {"only":1} using AppendMap
	b = AppendMap(b, map[string]int{"only": 1}, AppendString, AppendInt)

	// Read back and print
	seq, finish := ReadMapBytes(b, ReadStringBytes, ReadIntBytes)
	seq(func(k string, v int) bool {
		fmt.Printf("%s=%d\n", k, v)
		return true
	})
	if _, err := finish(); err != nil {
		fmt.Println("err:", err)
	}

	// Output:
	// only=1
}

var nilMsg = AppendNil(nil)
