Summary
A breach of contract is an error: A function is a unit of work. Thus, failures should be viewed as errors or otherwise based on their impact on functions. Within a function f , a failure is an error if and only if it violates one of f 's preconditions or prevents f from meeting any of its callees' preconditions, achieving any of f 's own postconditions, or reestablishing any invariant that f shares responsibility for maintaining.Item 68).
