Trait Implementations

impl Clone for ColumnExpr

fn clone(&self) -> ColumnExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnExpr

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

Formats the value using the given formatter.

impl Display for ColumnExpr

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

Formats the value using the given formatter.

impl Drive for ColumnExpr

fn drive<V: Visitor>(&self, visitor: &mut V)

impl DriveMut for ColumnExpr

fn drive_mut<V: VisitorMut>(&mut self, visitor: &mut V)

impl PartialEq for ColumnExpr

fn eq(&self, other: &ColumnExpr) -> 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.
