Function appendForEncoding

binlogreplication/binlog_json_serialization.go:295–302

appendForEncoding appends the |value| to the specified |bytes| and returns the updated byte slice. If |largeEncoding| is true, then 4 bytes are added to |bytes| to represent |value|, otherwise 2 bytes are used. This is a helper function for serializing the smallArray/largeArray and smallObject/large

(bytes []byte, value uint32, largeEncoding bool)

// This is a helper function for serializing the smallArray/largeArray and smallObject/largeObject formats, since
// they are identical formats, except that offsets, counts, and sizes are stored as 2 bytes in the small encodings,
// and stored as 4 bytes in the large encodings.
