pub struct InListExpr { /* private fields */ }

InList

Implementations

impl InListExpr

pub fn new( expr: Arc<dyn PhysicalExpr>, list: Vec<Arc<dyn PhysicalExpr>>, negated: bool, schema: &Schema ) -> Self

Create a new InList expression

pub fn expr(&self) -> &Arc<dyn PhysicalExpr>

Input expression

pub fn list(&self) -> &[Arc<dyn PhysicalExpr>]

List to search in

pub fn negated(&self) -> bool

Is this negated e.g. NOT IN LIST

Trait Implementations

impl Debug for InListExpr

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

Formats the value using the given formatter.

impl Display for InListExpr

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

Formats the value using the given formatter.

impl PartialEq<dyn Any + 'static> for InListExpr

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

impl PhysicalExpr for InListExpr

fn as_any(&self) -> &dyn Any

Return a reference to Any that can be used for downcasting

fn data_type(&self, _input_schema: &Schema) -> Result<DataType>

Get the data type of this expression, given the schema of the input

fn nullable(&self, input_schema: &Schema) -> Result<bool>

Determine whether this expression is nullable, given the schema of the input

fn evaluate(&self, batch: &RecordBatch) -> Result<ColumnarValue>

Evaluate an expression against a RecordBatch

fn children(&self) -> Vec<Arc<dyn PhysicalExpr>>

Get a list of child PhysicalExpr that provide the input for this expr.

fn with_new_children( self: Arc<Self>, children: Vec<Arc<dyn PhysicalExpr>> ) -> Result<Arc<dyn PhysicalExpr>>

Returns a new PhysicalExpr where all children were replaced by new exprs.

fn evaluate_selection( &self, batch: &RecordBatch, selection: &BooleanArray ) -> Result<ColumnarValue>

Evaluate an expression against a RecordBatch after first applying a validity array

fn analyze(&self, context: AnalysisContext) -> AnalysisContext

Return the boundaries of this expression. This method (and all the related APIs) are experimental and subject to change.

fn evaluate_bounds(&self, _children: &[&Interval]) -> Result<Interval>

Computes bounds for the expression using interval arithmetic.

fn propagate_constraints( &self, _interval: &Interval, _children: &[&Interval] ) -> Result<Vec<Option<Interval>>>

Updates/shrinks bounds for the expression using interval arithmetic. If constraint propagation reveals an infeasibility, returns None for the child causing infeasibility. If none of the children intervals change, may return an empty vector instead of cloning children.
