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(SignedExtensionMetadata metadata) {
int size = StrCodec.codec.sizeHint(metadata.identifier);
size += TypeIdCodec.codec.sizeHint(metadata.type);
size += TypeIdCodec.codec.sizeHint(metadata.additionalSigned);
return size;
}
