Struct datafusion_expr::expr::TryCast

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

TryCast Expression

Fields

expr: Box<Expr>

The expression being cast

data_type: DataType

The DataType the expression will yield

Implementations

impl TryCast

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

Create a new TryCast expression

Trait Implementations

impl Clone for TryCast

fn clone(&self) -> TryCast

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TryCast

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

Formats the value using the given formatter.

impl Hash for TryCast

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 for TryCast

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