Struct Cast 

pub struct Cast {
    pub expr: Box<Expr>,
    pub field: FieldRef,
}

Cast expression

Fields

expr: Box<Expr>

The expression being cast

field: FieldRef

The DataType the expression will yield

Implementations

impl Cast

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

Create a new Cast expression

pub fn new_from_field(expr: Box<Expr>, field: FieldRef) -> Self

Trait Implementations

impl Clone for Cast

fn clone(&self) -> Cast

Returns a duplicate 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

Formats the value using the given formatter.

impl Eq for Cast

impl Hash for Cast

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 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.

impl PartialOrd for Cast

fn partial_cmp(&self, other: &Cast) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
