Enums

Error

Errors returned by Sheet operations and propagation.

ErrorSite

Identifies a single sheet component an error implicates, for translating back to a source location. An Error’s sites() is an ordered list of these: the primary culprit first, followed by related context (e.g. the other method(s) and cell(s) involved in a structural conflict, or the remaining members of a cycle).
