Function ExampleReadMapBytes

msgp/iter_test.go:144–161

Example: reading a map[string]float64 from a byte slice using ReadMapBytes. It prints key=value pairs and then checks the remaining bytes/error from the returned closure.

func ExampleReadMapBytes() {
	var b []byte
	// Append {"pi":3.14, "e":2.718} using AppendMap - we use the sorted version for the example
	b = AppendMapSorted(b, map[string]float64{"pi": 3.14, "e": 2.718}, AppendString, AppendFloat64)

	seq, finish := ReadMapBytes(b, ReadStringBytes, ReadFloat64Bytes)

		fmt.Printf("%s=%.3f\n", k, v)
		return true

}

// Example: slice roundtrip with struct elements using WriteArray/ReadArray.
// Uses testDec as the element type, with EncoderTo/DecoderFrom helpers.
