Struct proof_of_sql::sql::postprocessing::SelectExpr

pub struct SelectExpr { /* private fields */ }

The select expression used to select, reorder, and apply alias transformations

Implementations

impl SelectExpr

pub fn new(aliased_result_exprs: Vec<AliasedResultExpr>) -> Self

Create a new SelectExpr node.

Trait Implementations

impl Clone for SelectExpr

fn clone(&self) -> SelectExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

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 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<S: Scalar> PostprocessingStep<S> for SelectExpr

fn apply( &self, owned_table: OwnedTable<S>, ) -> PostprocessingResult<OwnedTable<S>>

Apply the select transformation to the given OwnedTable.

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.
