Trait Implementations

impl Debug for Identity

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

Formats the value using the given formatter.

impl Display for Identity

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

Formats the value using the given formatter.

impl PartialEq<dyn Any> for Identity

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 Identity

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

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
