pub fn materialize(self) -> Result<SpecialEq<Arc<dyn ColumnsUdf>>, PolarsError>

Trait Implementations

impl<T> Clone for LazySerde<T>

where T: Clone,

fn clone(&self) -> LazySerde<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for LazySerde<T>

where T: Clone,

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

Formats the value using the given formatter.

impl<'a, T> Deserialize<'a> for LazySerde<T>

where T: Deserialize<'a> + Clone,

Available on crate feature serde only.

fn deserialize<D>( deserializer: D, ) -> Result<LazySerde<T>, <D as Deserializer<'a>>::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl<T> PartialEq for LazySerde<T>

where T: PartialEq + Clone,

fn eq(&self, other: &LazySerde<T>) -> 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<T> Serialize for LazySerde<T>

where T: Serialize + Clone,

Available on crate feature serde only.

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.
