Struct SetComparison 

pub struct SetComparison {
    pub expr: Box<Expr>,
    pub subquery: Subquery,
    pub op: Operator,
    pub quantifier: SetQuantifier,
}

Set comparison subquery (e.g. = ANY, > ALL)

Fields

expr: Box<Expr>

The expression to compare

subquery: Subquery

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

op: Operator

Comparison operator (e.g. =, >, <)

quantifier: SetQuantifier

Quantifier (ANY/ALL)

Implementations

impl SetComparison

pub fn new( expr: Box<Expr>, subquery: Subquery, op: Operator, quantifier: SetQuantifier, ) -> Self

Create a new set comparison expression

Trait Implementations

impl Clone for SetComparison

fn clone(&self) -> SetComparison

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetComparison

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

Formats the value using the given formatter.

impl Hash for SetComparison

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 SetComparison

fn eq(&self, other: &SetComparison) -> 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 SetComparison

fn partial_cmp(&self, other: &SetComparison) -> 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.
