Enum TypeKind 

pub enum TypeKind {
    Node,
    Edge,
    Attribute,
}

Kind of a registrable GTS type.

One of this crate’s closed enums: a fixed set that is stored as TEXT under a CHECK constraint and carried over REST as a plain string, so the storage form and the wire form are the same string. DESIGN § Closed Enum Contract is normative for all of them, and states the three rules a client depends on: a spelling never changes meaning and is never reused; adding a variant is compatible while removing or renaming one is breaking; and an unrecognized value must be carried through or refused by name, never mapped onto a known variant or defaulted – an unknown outcome decoded as ok turns a value the server chose into one it denied. The set is not an extension point: a deployment cannot add to it.
