Enum WindowSelectColumn 

#[non_exhaustive]
pub enum WindowSelectColumn {
    Measure {
        name: String,
        alias: String,
    },
    Dimension {
        path: String,
        alias: String,
    },
    Filter {
        name: String,
        alias: String,
    },
}

Column selection for window query (semantic names).

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.

Measure

Select a measure column (e.g., “revenue”)

Fields

name: String

alias: String

Result alias

Dimension

Select a dimension from JSONB (e.g., “category”)

Fields

path: String

Dimension path in JSONB

alias: String

Result alias

Filter

Select a denormalized filter column (e.g., “customer_id”, “occurred_at”)

alias: String

Result alias

Implementations

impl WindowSelectColumn

pub fn alias(&self) -> &str

Get the result alias for this selection.

Trait Implementations

impl Clone for WindowSelectColumn

fn clone(&self) -> WindowSelectColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowSelectColumn

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WindowSelectColumn

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WindowSelectColumn

fn eq(&self, other: &WindowSelectColumn) -> 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 WindowSelectColumn

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
