Enum ObjectId 

pub enum ObjectId {
    Table {
        table: NameKey,
    },
    Column {
        table: NameKey,
        column: NameKey,
    },
    Measure {
        table: NameKey,
        measure: NameKey,
    },
    Hierarchy {
        table: NameKey,
        hierarchy: NameKey,
    },
    Partition {
        table: NameKey,
        partition: NameKey,
    },
    Relationship {
        from_table: NameKey,
        from_column: NameKey,
        to_table: NameKey,
        to_column: NameKey,
    },
    Role {
        role: NameKey,
    },
    CalculationItem {
        table: NameKey,
        item: NameKey,
    },
    Expression {
        name: NameKey,
    },
    Function {
        name: NameKey,
    },
    ReportMeasure {
        measure: NameKey,
    },
}

Stable, case-insensitive identity of a model or report object — the node key of the dependency graph.

Every name is a NameKey, so two ObjectIds that differ only in casing are the same node. Ordering (used to give analysis output a deterministic order) follows the folded names, never the original casing.

Variants

Table

A table.

Fields

table: NameKey

Table name.

Column

A column, identified by its owning table.

Fields

table: NameKey

Owning table.

column: NameKey

Column name.

Measure

A measure. The home table is part of the identity for display purposes only; the engine guarantees measure names are unique across the whole model.

Fields

table: NameKey

Home table.

measure: NameKey

Measure name.

Hierarchy

A hierarchy defined on a table.

Fields

table: NameKey

Owning table.

hierarchy: NameKey

Hierarchy name.

Partition

A partition (Power Query / M source) of a table.

Fields

table: NameKey

Owning table.

partition: NameKey

Partition name.

Relationship

A relationship, identified by its endpoints. TMDL relationship names are GUIDs kept for diagnostics only, and a column pair carries at most one relationship, so the four endpoint names are the stable identity.

Fields

from_table: NameKey

Table on the “from” (typically many) side.

from_column: NameKey

Key column in from_table.

to_table: NameKey

Table on the “to” (typically one) side.

to_column: NameKey

Key column in to_table.

Role

A security role.

Fields

role: NameKey

Role name.

CalculationItem

An item of a calculation group, identified by the calculation group’s table.

Fields

table: NameKey

Calculation group table.

item: NameKey

Calculation item name.

Expression

A shared model-level M expression (e.g. a parameter or a shared query).

Fields

name: NameKey

Expression name.

Function

A user-defined DAX function (TOM function). Names are model-global.

Fields

name: NameKey

Function name.

ReportMeasure

A report-level measure (reportExtensions.json). Lives in the report, not the model, so it does not share the model’s measure namespace: a distinct variant avoids ever conflating the two.

Fields

measure: NameKey

Report measure name; unique within its report.

Implementations

impl ObjectId

pub fn owning_table(&self) -> Option<&NameKey>

The model table this object belongs to — a relationship reports its “from” side, and objects with no model table (roles, shared expressions, functions, report measures) have none. The name is data, not display: render it with NameKey::quoted for the single-quoted form the finding ids use.

Trait Implementations

impl Clone for ObjectId

fn clone(&self) -> ObjectId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectId

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

Formats the value using the given formatter.

impl Display for ObjectId

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

Human-readable form for diagnostics. Quoted names use the same '' escaping as FieldRef; bracketed names are unescaped for the same reason.

impl Eq for ObjectId

impl Hash for ObjectId

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 Ord for ObjectId

fn cmp(&self, other: &ObjectId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ObjectId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ObjectId

fn partial_cmp(&self, other: &ObjectId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
