Validated GROUP BY expression

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

JsonbPath

JSONB dimension extraction

Fields

jsonb_column: String

JSONB column name (usually “data”)

path: String

Path to extract (e.g., “category”)

alias: String

Result alias

TemporalBucket

Temporal bucket with DATE_TRUNC

Fields

column: String

Timestamp column name

bucket: TemporalBucket

Bucket type

alias: String

Result alias

CalendarPath

Pre-computed calendar dimension extraction

Fields

calendar_column: String

Calendar JSONB column (e.g., “date_info”)

json_key: String

JSON key within calendar column (e.g., “month”)

alias: String

Result alias

NativeColumn

A native SQL column on the view/fact table — referenced directly, not via JSONB extraction. Generates a dialect-quoted column reference in GROUP BY / SELECT, enabling btree index usage.

Fields

column: String

Column name as it appears in the CREATE VIEW DDL.

pg_cast: String

PostgreSQL type suffix for casting (e.g. "uuid", "int8", "").

alias: String

Alias used in SELECT and referenced by ORDER BY.

Trait Implementations

impl Clone for GroupByExpression

fn clone(&self) -> GroupByExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupByExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GroupByExpression

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for GroupByExpression

impl PartialEq for GroupByExpression

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for GroupByExpression

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
