Enum StructuralEdge 

pub enum StructuralEdge {
    TableMember,
    TablePartition,
    Relationship,
    RelationshipEndpoint,
    SortByColumn,
    GroupByColumn,
    HierarchyLevel,
    EngineManaged,
    RolePermission,
}

The structural rule an edge came from.

Variants

TableMember

The source is defined on the target table; a used member keeps its table alive.

TablePartition

The table loads its rows through this partition.

Relationship

The relationship hangs off this table; either endpoint keeps it alive.

RelationshipEndpoint

The relationship needs this key column.

SortByColumn

The source column is sorted by the target column.

GroupByColumn

The source column is grouped by the target column.

HierarchyLevel

The hierarchy drills down through this column.

EngineManaged

The column is materialized by the engine together with its table (calculated-table columns, calculation-group columns, calendar columns) and cannot be dropped independently.

RolePermission

The role grants access to this table.
