msgp/iter_test.go:165–190

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

// Example: map roundtrip with struct values using WriteMapSorted/ReadMap.
// Uses testDec as the value type and sorts keys for deterministic output.
