- Exception_safety abstract "Exception safety guarantees, originally formalized by David Abrahams, are a set of contractual guidelines that class library implementers and clients use when reasoning about exception handling safety in C++ programs. The principles are not restricted to C++ though, and also apply to any programming language that uses exceptions.There are several levels of exception safety (in decreasing order of safety): No-throw guarantee, also known as failure transparency: Operations are guaranteed to succeed and satisfy all requirements even in presence of exceptional situations. If an exception occurs, it will be handled internally and not observed by clients. Strong exception safety, also known as commit or rollback semantics: Operations can fail, but failed operations are guaranteed to have no side effects so all data retain original values. Basic exception safety, also known as no-leak guarantee: Partial execution of failed operations can cause side effects, but all invariants are preserved and no resources are leaked. Any stored data will contain valid values, even if data has different values now from before the exception. No exception safety: No guarantees are made.Usually, at least basic exception safety is required to write robust code. Higher levels of safety can sometimes be difficult to achieve, and might incur an overhead due to extra copying.".
