Trait Implementations

impl AnalysisExpr for RowIdxExpr

fn stat_falsification( &self, _catalog: &mut dyn StatsCatalog, ) -> Option<Arc<dyn VortexExpr>>

An expression over zone-statistics which implies all records in the zone evaluate to false.

fn max(&self, _catalog: &mut dyn StatsCatalog) -> Option<Arc<dyn VortexExpr>>

An expression for the upper non-null bound of this expression, if available.

fn min(&self, _catalog: &mut dyn StatsCatalog) -> Option<Arc<dyn VortexExpr>>

An expression for the lower non-null bound of this expression, if available.

fn nan_count( &self, _catalog: &mut dyn StatsCatalog, ) -> Option<Arc<dyn VortexExpr>>

An expression for the NaN count for a column, if available.

fn field_path(&self) -> Option<FieldPath>

impl AsRef<dyn VortexExpr> for RowIdxExpr

fn as_ref(&self) -> &dyn VortexExpr

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for RowIdxExpr

fn clone(&self) -> RowIdxExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowIdxExpr

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

Formats the value using the given formatter.

impl Deref for RowIdxExpr

type Target = dyn VortexExpr

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for RowIdxExpr

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

Formats the value using the given formatter.

impl From<RowIdxExpr> for ExprRef

fn from(value: RowIdxExpr) -> ExprRef

Converts to this type from the input type.

impl Hash for RowIdxExpr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoExpr for RowIdxExpr

fn into_expr(self) -> ExprRef

Convert this type into an expression reference.

impl PartialEq for RowIdxExpr

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