Struct CategoricalMetadata 

pub struct CategoricalMetadata {
    pub categories: Vec<Scalar>,
    pub ordered: bool,
}

Metadata for categorical (factor) data.

Stores the unique category values and an ordered flag. The underlying Series column contains integer codes (indices into categories). Series-level dtype reporting still surfaces DType::Categorical.

Fields

categories: Vec<Scalar>

The unique category values, in order.

ordered: bool

Whether the categories have a meaningful total ordering.

Trait Implementations

impl Clone for CategoricalMetadata

fn clone(&self) -> CategoricalMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CategoricalMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CategoricalMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CategoricalMetadata

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
