- * A [Codec] encodes and (if supported) decodes data.
- *
- * Codecs can be fused. For example fusing [JSON] and [UTF8] produces
- * an encoder that can convert Json objects directly to bytes, or can decode
- * bytes directly to json objects.
- *
- * Fused codecs generally attempt to optimize the operations and can be faster
- * than executing each step of an encoding separately.
- *
- * *Codecs are still experimental and are subject to change without notice.*
