While we can provide relatively safe interfaces to protect users from misusing the API, it's harder to be absolutely certain that the number of bytes compile says a function needs is the number of bytes emit_to_memory actually writes for that function.

One option would be to provide a safe checked version of MemoryCodeSink. However, it's also worth considering evaluating available crates that provide low-level byte buffer writing functionality, including:
