Struct datafusion_python::datafusion_expr::Cast

pub struct Cast {
    pub expr: Box<Expr>,
    pub data_type: DataType,
}

Cast expression

Fields

expr: Box<Expr>

The expression being cast

data_type: DataType

The DataType the expression will yield

Implementations

impl Cast

pub fn new(expr: Box<Expr>, data_type: DataType) -> Cast

Create a new Cast expression

Trait Implementations

impl Clone for Cast

fn clone(&self) -> Cast

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cast

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

Formats the value using the given formatter.

impl From<Cast> for PyCast

fn from(cast: Cast) -> PyCast

Converts to this type from the input type.

impl From<PyCast> for Cast

fn from(cast: PyCast) -> Self

Converts to this type from the input type.

impl Hash for Cast

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 Cast

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