Function ExampleReadArrayBytes_struct

msgp/iter_test.go:225–246

Example: slice roundtrip with struct elements in a byte slice using AppendArray/ReadArrayBytes. Uses testDec as the element type, with EncoderToBytes/DecoderFromBytes helpers.

// Uses testDec as the value type and sorts keys for deterministic output.
