Enum ErrorSite 

#[non_exhaustive]
pub enum ErrorSite {
    MethodIndex(usize),
    Method(RelationshipId, usize),
    Relationship(RelationshipId),
    Cell(CellId),
}

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).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MethodIndex(usize)

Index into the methods Vec passed to add_relationship, before any RelationshipId exists for it.

Method(RelationshipId, usize)

A method within an already-registered relationship.

Relationship(RelationshipId)

A relationship as a whole (no single method within it is implicated).

Cell(CellId)

A single cell.
