Struct RowFilter

pub struct RowFilter { /* private fields */ }

Implementations

impl RowFilter

pub fn new(expr: ExprRef) -> Self

pub fn new_expr(expr: ExprRef) -> ExprRef

pub fn from_conjunction(conjunction: Vec<ExprRef>) -> Self

Create a new row filter from a conjunction. The conjunction must have length > 0.

pub fn from_conjunction_expr(conjunction: Vec<ExprRef>) -> Arc<Self>

Create a new row filter from a conjunction. The conjunction must have length > 0.

pub fn only_fields(&self, fields: &[Field]) -> Option<Self>

Trait Implementations

impl Clone for RowFilter

fn clone(&self) -> RowFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowFilter

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

Formats the value using the given formatter.

impl Display for RowFilter

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

Formats the value using the given formatter.

impl PartialEq<dyn Any> for RowFilter

fn eq(&self, other: &dyn Any) -> 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 PartialEq for RowFilter

fn eq(&self, other: &Self) -> 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 VortexExpr for RowFilter

fn as_any(&self) -> &dyn Any

Convert expression reference to reference of Any type

fn evaluate(&self, batch: &ArrayData) -> VortexResult<ArrayData>

Compute result of expression on given batch producing a new batch

fn collect_references<'a>(&'a self, references: &mut HashSet<&'a Field>)

Accumulate all field references from this expression and its children in the provided set

fn references(&self) -> HashSet<&Field>

Accumulate all field references from this expression and its children in a new set
