public sealed class FieldCodec<T>An encode/decode pair for a single field. This effectively encapsulates all the information needed to read or write the field value from/to a coded stream.
This class is public and has to be as it is used by generated code, but its public API is very limited - just what the generated code needs to call directly.

Remarks
This never writes default values to the stream, and does not address "packedness" in repeated fields itself, other than to know whether or not the field should be packed.
