Struct SparseDType 

pub struct SparseDType {
    pub value_dtype: DType,
    pub fill_value: Scalar,
}

Fields

value_dtype: DType

fill_value: Scalar

Implementations

impl SparseDType

pub fn new(value_dtype: DType, fill_value: Scalar) -> Result<Self, TypeError>

Construct a pandas-style sparse dtype descriptor.

This records the logical dense value dtype plus the scalar value that is elided from storage. The concrete sparse column representation lives in fp-columnar; this descriptor is the shared public contract.

Trait Implementations

impl Clone for SparseDType

fn clone(&self) -> SparseDType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseDType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SparseDType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparseDType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
