Struct ExprInSubquery 

pub struct ExprInSubquery {
    pub expr: Box<Expr>,
    pub query: Box<Query>,
}

Tests whether a value is in the results of a subquery.

Returns true if expr matches any row returned by query.

Examples

in_subquery(x, select(...))  // returns `true` if `x` is in the subquery results

Fields

expr: Box<Expr>

The value to search for.

query: Box<Query>

The subquery to search within.

Trait Implementations

impl Clone for ExprInSubquery

fn clone(&self) -> ExprInSubquery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprInSubquery

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

Formats the value using the given formatter.

impl From<ExprInSubquery> for Expr

fn from(value: ExprInSubquery) -> Expr

Converts to this type from the input type.

impl Node for ExprInSubquery

fn visit<V>(&self, visit: V)

where V: Visit,

fn visit_mut<V>(&mut self, visit: V)

where V: VisitMut,

impl PartialEq for ExprInSubquery

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