Struct Dimension 

pub struct Dimension { /* private fields */ }

Represents a dimension in the cube

A dimension is a categorical attribute used for slicing and dicing data (e.g., date, region, product category).

Implementations

impl Dimension

pub fn new(name: impl Into<String>, data_type: DataType) -> Self

Create a new dimension

pub fn with_config( name: impl Into<String>, data_type: DataType, nullable: bool, cardinality: Option<usize>, description: Option<String>, ) -> Self

Create a new dimension with full configuration

pub fn name(&self) -> &str

Get the dimension name

pub fn data_type(&self) -> &DataType

Get the data type

pub fn cardinality(&self) -> Option<usize>

Get the cardinality

pub fn is_nullable(&self) -> bool

Check if the dimension is nullable

pub fn description(&self) -> Option<&str>

Get the description

pub fn set_cardinality(&mut self, cardinality: usize)

Set the cardinality

pub fn set_description(&mut self, description: impl Into<String>)

Set the description

pub fn with_cardinality(self, cardinality: usize) -> Self

Builder-style: set cardinality

pub fn with_nullable(self, nullable: bool) -> Self

Builder-style: set nullable

pub fn with_description(self, description: impl Into<String>) -> Self

Builder-style: set description

Trait Implementations

impl Clone for Dimension

fn clone(&self) -> Dimension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dimension

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Dimension

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Dimension

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
