Trait Implementations

impl Clone for SelectResultExpr

fn clone(&self) -> SelectResultExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SelectResultExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SelectResultExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AliasedResultExpr> for SelectResultExpr

fn from(value: AliasedResultExpr) -> Self

Converts to this type from the input type.

impl From<SelectResultExpr> for SelectItem

fn from(select: SelectResultExpr) -> Self

Converts to this type from the input type.

impl PartialEq for SelectResultExpr

fn eq(&self, other: &SelectResultExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
