Trait Implementations

impl Clone for FunctionExpr

fn clone(&self) -> FunctionExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionExpr

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

Formats the value using the given formatter.

impl Display for FunctionExpr

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

Formats the value using the given formatter.

impl From<BinaryFunction> for FunctionExpr

fn from(b: BinaryFunction) -> FunctionExpr

Converts to this type from the input type.

impl From<BooleanFunction> for FunctionExpr

fn from(func: BooleanFunction) -> FunctionExpr

Converts to this type from the input type.

impl From<CategoricalFunction> for FunctionExpr

fn from(func: CategoricalFunction) -> FunctionExpr

Converts to this type from the input type.

impl From<FunctionExpr> for SpecialEq<Arc<dyn SeriesUdf>>

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

Converts to this type from the input type.

impl From<StringFunction> for FunctionExpr

fn from(str: StringFunction) -> FunctionExpr

Converts to this type from the input type.

impl Hash for FunctionExpr

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 FunctionExpr

fn eq(&self, other: &FunctionExpr) -> 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.
