GetElementOneOfProtos returns all one of protos.

GetElementTypes returns all element types.

GetNonTransientEquivalent is the reciprocal of GetTransientEquivalent and therefore take a TRANSIENT_ Status as input.

GetTransientEquivalent returns the equivalent TRANSIENT_ Status for a given status.

HasDeprecatedElements returns if the target contains any element or fields marked for deprecation.

MakeCurrentStateFromDescriptors constructs a CurrentState object from a slice of DescriptorState object from which the current state has been decomposed.

MakeTarget constructs a new Target.

MigrateCurrentState migrates a current state by upgrading elements based on the current version number.

MigrateDescriptorState migrates descriptor state and applies any changes relevant for the current cluster version.

NewElementCollection constructs a generic element collection containing the elements in `g` listed in the `indexes` slice.

InvalidTarget indicates that the element doesn't have a target status for the current schema change.

PlaceHolderRoleName placeholder string for non-fetched role names.

ToAbsent indicates that the element should have status ABSENT after completion of the current schema change, meaning it should no longer exist.

ToPublic indicates that the element should have status PUBLIC after completion of the current schema change, meaning it should exist and not in any kind of transitory state.

Transient is like ToAbsent in that the element should no longer exist once the schema change is done.

NumStatus is the number of values which Status may take on.

CurrentState is a TargetState decorated with the current status of the elements in the target state.

ElementCollection represents an ordered set of (current status, target status, element) tuples, looked up in `g` by iterating through `indexes`.

Element represents a logical component of a catalog entry's schema (e.g., an index or column in a table).

ElementCollectionGetter abstracts the actual mechanism for obtaining (current status, target status, element) tuples in an element collection.

HumanReadableNameProvider maps IDs to human-readable names for the purpose of decorating EXPLAIN(DDL) and other human-readable output.

NameMappings implements the HumanReadableNameProvider interface.

SourceElementID elements ID's for identifying parent elements.

TargetStatus is the subset of Status values which serve as valid target statuses.
