Strong exception safety, also known as commit or rollback semantics: Operations can fail, but failed operations are guaranteed to have no side effects, leaving the original values intact. [9] Basic exception safety: Partial execution of failed operations can result in side effects, but all invariants are preserved. Any stored data will contain ...
