Struct Measure 

pub struct Measure { /* private fields */ }

Represents a measure in the cube

A measure is a numeric value that can be aggregated (e.g., sales amount, quantity, revenue).

Implementations

impl Measure

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

Create a new measure with a default aggregation function

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

Create a new measure with full configuration

pub fn name(&self) -> &str

Get the measure name

pub fn data_type(&self) -> &DataType

Get the data type

pub fn default_agg(&self) -> AggFunc

Get the default aggregation function

pub fn is_nullable(&self) -> bool

Check if the measure is nullable

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

Get the description

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

Get the format string

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

Set the description

pub fn set_format(&mut self, format: impl Into<String>)

Set the format

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

pub fn with_format(self, format: impl Into<String>) -> Self

Builder-style: set format

pub fn validate(&self) -> Result<(), String>

Validate that the default aggregation is compatible with the data type

Trait Implementations

impl Clone for Measure

fn clone(&self) -> Measure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Measure

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Measure

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Measure

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
