Trait Implementations

impl Clone for CategoricalFunction

fn clone(&self) -> CategoricalFunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CategoricalFunction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CategoricalFunction

fn deserialize<__D>( __deserializer: __D, ) -> Result<CategoricalFunction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CategoricalFunction

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

Formats the value using the given formatter.

impl From<CategoricalFunction> for FunctionExpr

fn from(func: CategoricalFunction) -> FunctionExpr

Converts to this type from the input type.

impl From<CategoricalFunction> for SpecialEq<Arc<dyn ColumnsUdf>>

fn from(func: CategoricalFunction) -> SpecialEq<Arc<dyn ColumnsUdf>>

Converts to this type from the input type.

impl Hash for CategoricalFunction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CategoricalFunction

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CategoricalFunction

impl StructuralPartialEq for CategoricalFunction
