Struct datafusion::logical_expr::expr::InSubquery

pub struct InSubquery {
    pub expr: Box<Expr>,
    pub subquery: Subquery,
    pub negated: bool,
}

IN subquery

Fields

expr: Box<Expr>

The expression to compare

subquery: Subquery

Subquery that will produce a single column of data to compare against

negated: bool

Whether the expression is negated

Implementations

impl InSubquery

pub fn new(expr: Box<Expr>, subquery: Subquery, negated: bool) -> InSubquery

Create a new InSubquery expression

Trait Implementations

impl Clone for InSubquery

fn clone(&self) -> InSubquery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InSubquery

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

Formats the value using the given formatter.

impl Hash for InSubquery

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 InSubquery

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