Trait Implementations

impl Clone for SetOperator

fn clone(&self) -> SetOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetOperator

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

Formats the value using the given formatter.

impl From<SetOperator> for SetOperator

fn from(op: SetOperator) -> Self

Converts to this type from the input type.

impl PartialEq for SetOperator

fn eq(&self, other: &SetOperator) -> 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 ToSql for SetOperator

fn to_sql(&self) -> String

Convert this AST node to a SQL string
