sizeHint method
If possible give a hint of expected size of the encoding.
This method is used inside default implementation of encode
to avoid re-allocations.
Implementation
@override
int sizeHint(Field value) {
int size = OptionCodec(StrCodec.codec).sizeHint(value.name);
size += TypeIdCodec.codec.sizeHint(value.type);
size += OptionCodec(StrCodec.codec).sizeHint(value.typeName);
size += SequenceCodec(StrCodec.codec).sizeHint(value.docs);
return size;
