Implementations

impl SetExpr

pub fn span(&self) -> Span

pub fn into_query(self) -> Query

Trait Implementations

impl Clone for SetExpr

fn clone(&self) -> SetExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetExpr

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

Formats the value using the given formatter.

impl Display for SetExpr

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

Formats the value using the given formatter.

impl Drive for SetExpr

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

impl DriveMut for SetExpr

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

impl PartialEq for SetExpr

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