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 expr_stats(&self) -> Arc<dyn PhysicalExprStats>

Return the expression statistics for this expression. This API is currently experimental.
