Converts to this type from the input type.

impl From<FunctionExpr> for SpecialEq<Arc<dyn SeriesUdf + 'static>>

fn from(func: FunctionExpr) -> SpecialEq<Arc<dyn SeriesUdf + 'static>>

Converts to this type from the input type.

impl From<NanFunction> for SpecialEq<Arc<dyn SeriesUdf + 'static>>

fn from(nan_function: NanFunction) -> SpecialEq<Arc<dyn SeriesUdf + 'static>>

Converts to this type from the input type.

impl From<StringFunction> for SpecialEq<Arc<dyn SeriesUdf + 'static>>

Available on crate feature strings only.

fn from(func: StringFunction) -> SpecialEq<Arc<dyn SeriesUdf + 'static>>

Converts to this type from the input type.

impl<T> PartialEq<SpecialEq<Arc<T>>> for SpecialEq<Arc<T>>where
    T: ?Sized,

fn eq(&self, other: &SpecialEq<Arc<T>>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<SpecialEq<Series>> for SpecialEq<Series>

fn eq(&self, other: &SpecialEq<Series>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
