Function ExampleReadMap

msgp/iter_test.go:71–93

Example: reading a map[string]int using ReadMap with a *Reader. It prints key=value pairs in the same order they were written.

// It prints key=value pairs in the same order they were written.
func ExampleReadMap() {
	var buf bytes.Buffer
	w := NewWriter(&buf)

	// Write a map {"a":1, "b":2} using WriteMap - we use the sorted version so output is predictable.
	_ = WriteMapSorted(w, map[string]int{"a": 1, "b": 2}, w.WriteString, w.WriteInt)
	_ = w.Flush()

	r := NewReader(&buf)

	seq, done := ReadMap(r, r.ReadString, r.ReadInt)
	seq(func(k string, v int) bool {
		fmt.Printf("%s=%d\n", k, v)
		return true
	})

// Example: writing a map using WriteMap (non-sorted).
// Uses a single-entry map to keep output deterministic.
