Fields

fun: Arc<ScalarUDF>

The function

args: Vec<Expr>

List of expressions to feed to the functions as arguments

Implementations

impl ScalarUDF

pub fn new(fun: Arc<ScalarUDF>, args: Vec<Expr>) -> Self

Create a new ScalarUDF expression

Trait Implementations

impl Clone for ScalarUDF

fn clone(&self) -> ScalarUDF

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarUDF

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

Formats the value using the given formatter.

impl Hash for ScalarUDF

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

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<ScalarUDF> for ScalarUDF

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