Implementations

impl SelectExpr

pub fn new_from_aliased_result_exprs( aliased_exprs: &[AliasedResultExpr], ) -> Self

Create a new select expression from a slice of AliasedResultExpr

pub fn new_from_expressions(exprs: &[Expression]) -> Self

Create a new select expression from a slice of Expressions

Trait Implementations

impl Debug for SelectExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl DynPartialEq for SelectExpr

fn as_any(&self) -> &dyn Any

fn box_eq(&self, other: &dyn Any) -> bool

impl PartialEq for SelectExpr

fn eq(&self, other: &SelectExpr) -> 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 RecordBatchExpr for SelectExpr

fn apply_transformation(&self, record_batch: RecordBatch) -> Option<RecordBatch>

Apply the transformation to the RecordBatch and return the result.

impl Serialize for SelectExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
