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(ApiMetadata metadata) {
int size = StrCodec.codec.sizeHint(metadata.name);
size += SequenceCodec(ApiMethodMetadata.codec).sizeHint(metadata.methods);
size += SequenceCodec(StrCodec.codec).sizeHint(metadata.docs);
return size;
}
