Enum PartitionSource 

pub enum PartitionSource {
    M {
        expression: String,
    },
    Calculated {
        expression: String,
    },
    Query {
        query: String,
    },
    Other {
        kind: Option<String>,
    },
}

A partition’s source query, discriminated by query language.

Variants

M

Power Query (TOM m).

Fields

expression: String

M expression text.

Calculated

DAX — this is what makes a table a calculated table (TOM calculated).

Fields

expression: String

DAX expression producing the table.

Query

Legacy native query partition (TOM query).

Fields

query: String

Native query text, in the data source’s own dialect.

Other

entity (DirectLake), inferred, future kinds — schema drift never panics; the raw kind string is kept for diagnostics.

Fields

kind: Option<String>

The source kind as written in the model, when one was present.

Trait Implementations

impl Clone for PartitionSource

fn clone(&self) -> PartitionSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionSource

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

Formats the value using the given formatter.

impl Default for PartitionSource

fn default() -> Self

An unparsed source is Other, never a query language, so an unrecognized partition can never be mistaken for DAX or M by the expression enumeration.

impl Eq for PartitionSource

impl PartialEq for PartitionSource

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

Equality operator ==.

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

Inequality operator !=.
