Struct Variation 

pub struct Variation {
    pub name: String,
    pub is_default: bool,
    pub relationship: Option<String>,
    pub default_hierarchy: Option<HierarchyRef>,
}

A column variation (TOM variation): the model’s declaration that the owning column is served by a hierarchy on another table — for auto date/time, a hidden relationship to an engine-generated LocalDateTable_*.

Report bindings written against the varied column resolve through this declaration: the graph joins the referenced relationship or hierarchy instead of guessing which of a column’s relationships is the variation.

Fields

name: String

Variation name (the TMDL descriptor name, e.g. Variation).

is_default: bool

Whether this is the column’s default variation (TOM isDefault; TMDL writes the key only when true).

relationship: Option<String>

Name of the TOM relationship realizing this variation — for auto date/time, the hidden relationship from the owning column to the date table’s key column. TMDL relationship names are GUIDs.

default_hierarchy: Option<HierarchyRef>

The table-qualified default hierarchy (TOM defaultHierarchy), e.g. LocalDateTable_x.'Date Hierarchy' — where report bindings on the varied column land.
