}

One difference between the committed model and a fresh survey, named by what changed rather than which lines did. Ids are as the file writes them; kinds are the specification’s keywords.

Variants

ElementAdded

Fields

id: String

kind: String

ElementRemoved

Fields

id: String

kind: String

ElementChanged

An element in both, with the fields that differ in the order emit writes them; kind is the fresh one, kind_was the committed one when it changed.

Fields

id: String

kind: String

kind_was: Option<String>

fields: Vec<ElementField>

RelationAdded

Fields

from: String

to: String

kind: String

RelationRemoved

Fields

from: String

to: String

kind: String

RelationChanged

A relation in both: its fresh kind and the committed one when it changed, whether its label changed and the names it gained and lost, and whether its technology changed. The names are the label split on , (a surveyed relation’s items, an external’s title in its pieces), so they describe a label change; a reorder or a repeat changes the label with none gained or lost.

Fields

from: String

to: String

kind: String

kind_was: Option<String>

label: bool

gained: Vec<String>

lost: Vec<String>

technology: bool
