drift

Library to compare two OpenAPI documents to detect changes between them. Those changes may be classified as backward-incompatible, forward-incompatible, incompatible (i.e. both backward- and forward-incompatible), trivial (e.g. changes to document layout or metadata), or unhandled. Unhandled changes are those where structures are non-identical and drift has either not yet been extended to detect fine-grained compatibility, or where compatibility checks may not be feasible (e.g. comparing the intersection of two regular expressions).
