Trait Implementations

impl<'a> Debug for Operand<'a>

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

Formats the value using the given formatter.

impl Expression for Operand<'_>

fn write_query( &self, writer: &dyn SqlWriter, context: &mut Context, buff: &mut String, )

fn is_ordered(&self) -> bool

impl OpPrecedence for Operand<'_>

fn precedence(&self, _writer: &dyn SqlWriter) -> i32

impl PartialEq for Operand<'_>

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