// Equal reports whether two messages are equal,
// by recursively comparing the fields of the message.
//
// - Bytes fields are equal if they contain identical bytes.
// Empty bytes (regardless of nil-ness) are considered equal.
//
// - Floating-point fields are equal if they contain the same value.
// Unlike the == operator, a NaN is equal to another NaN.
//
// - Other scalar fields are equal if they contain the same value.
//
// - Message fields are equal if they have
// the same set of populated known and extension field values, and
// the same set of unknown fields values.
//
// - Lists are equal if they are the same length and
// each corresponding element is equal.
//
// - Maps are equal if they have the same set of keys and
// the corresponding value for each key is equal.
//
// An invalid message is not equal to a valid message.
// An invalid message is only equal to another invalid message of the
// same type. An invalid message often corresponds to a nil pointer
// of the concrete message type. For example, (*pb.M)(nil) is not equal
// to &pb.M{}.
// If two valid messages marshal to the same bytes under deterministic
// serialization, then Equal is guaranteed to report true.
