Trait Implementations

impl AnalysisExpr for BinaryExpr

fn stat_falsification(&self, catalog: &mut dyn StatsCatalog) -> Option<ExprRef>

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

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

If an expression is returned, its value is an upper bound on the value of expr.

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

If an expression is returned, its value is an upper bound on the value of expr. see AnalysisExpr::max

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

impl Clone for BinaryExpr

fn clone(&self) -> BinaryExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryExpr

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

Formats the value using the given formatter.

impl Display for BinaryExpr

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

Formats the value using the given formatter.

impl Hash for BinaryExpr

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 PartialEq for BinaryExpr

fn eq(&self, other: &BinaryExpr) -> 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 BinaryExpr

fn as_any(&self) -> &dyn Any

Convert expression reference to reference of Any type

fn unchecked_evaluate(&self, scope: &Scope) -> VortexResult<ArrayRef>

Compute result of expression on given batch producing a new batch

fn children(&self) -> Vec<&ExprRef>

fn replacing_children(self: Arc<Self>, children: Vec<ExprRef>) -> ExprRef

fn return_dtype(&self, ctx: &ScopeDType) -> VortexResult<DType>

Compute the type of the array returned by VortexExpr::evaluate.

fn evaluate(&self, scope: &Scope) -> VortexResult<ArrayRef>

Compute result of expression on given batch producing a new batch

impl Eq for BinaryExpr
