Struct datafusion_physical_expr::expressions::InListExpr

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.
