Type Alias KeysSharingField<T, K, Field>

KeysSharingField: {
    [J in Exclude<keyof T, K>]: AreEqualLiterals<T[J][Field], T[K][Field]> extends true
        ? J
        : never
}[Exclude<keyof T, K>]

The other declaration keys whose Field literal equals one entry's — the table-scoped uniqueness check both vectorAttribute and name use.
