Enum FieldTarget 

pub enum FieldTarget {
    Column {
        table: NameKey,
        column: NameKey,
    },
    Measure {
        home_table: Option<NameKey>,
        measure: NameKey,
    },
    HierarchyLevel {
        table: NameKey,
        hierarchy: NameKey,
        level: NameKey,
        via_column: Option<NameKey>,
        via_variation: Option<NameKey>,
    },
    Aggregation {
        function: Option<String>,
        inner: Box<FieldTarget>,
    },
    Written(FieldRef),
}

A model-object reference as written in a report binding, before resolution.

PBIR bindings are structured JSON entity trees (Column, Measure, HierarchyLevel, Aggregation); legacy Layout binds written names. Both normalize here, so downstream code never branches on source format.

The column/measure discrimination is kept rather than collapsed into FieldRef, because the binding states it outright and resolution would otherwise be guessing.

Variants

Column

A column, by its table (SourceRef.Entity) and name (Property).

Fields

table: NameKey

Owning table as written.

column: NameKey

Column name as written.

Measure

A measure, by name. Measures are model-global; the entity PBIR writes alongside them is the home table as displayed, carried for provenance only.

Fields

home_table: Option<NameKey>

Home table as written, if any.

measure: NameKey

Measure name as written.

HierarchyLevel

A hierarchy level: the level a visual drills to, which keeps the whole hierarchy (and its level columns) alive.

Fields

table: NameKey

Owning table as written. For a hierarchy reached over a column variation this is the varied (base) table; the hierarchy itself lives on the variation’s target table.

hierarchy: NameKey

Hierarchy name as written.

level: NameKey

Level name as written.

via_column: Option<NameKey>

The varied column (PBIR PropertyVariationSource.Property), when the hierarchy is reached over a column variation — the key that joins this binding to the model-side crate::model::Column::variations declaration.

via_variation: Option<NameKey>

The variation’s name (PBIR PropertyVariationSource.Name), which picks between a column’s variations when there are several.

Aggregation

An aggregation over an inner reference, e.g. Sum of 'Sales'[Units]. The inner target is what stays alive; the function is diagnostics.

Fields

function: Option<String>

Aggregation function as written, e.g. "Sum".

inner: Box<FieldTarget>

The aggregated field.

Written(FieldRef)

A written name the parser could not structure — legacy Layout strings, unresolved query aliases. Kept anyway: a binding we cannot read is still a binding, and dropping it would under-count roots.

Trait Implementations

impl Clone for FieldTarget

fn clone(&self) -> FieldTarget

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldTarget

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FieldTarget

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Human-readable form for diagnostics, quoting names the way FieldRef does. The hierarchy-level and aggregation forms are illustrative, not valid DAX — level references have no DAX syntax.

impl Eq for FieldTarget

impl Hash for FieldTarget

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FieldTarget

fn eq(&self, other: &FieldTarget) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for FieldTarget
