The reftable/ directory is structured as a library, so it cannot crash on misuse. Instead, it returns an error code. In addition to signaling errors, the error code can be used to signal conditions from lower levels of the library to be handled by higher levels of the library. For example, in a transaction we might legitimately write an empty reftable file, but in that case, we want to shortcut the transaction.
