Implementations

impl CheckComparisonOp

pub fn as_sql_str(self) -> &'static str

SQL spelling for this comparison operator.

Trait Implementations

impl Clone for CheckComparisonOp

fn clone(&self) -> CheckComparisonOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CheckComparisonOp

impl Debug for CheckComparisonOp

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

Formats the value using the given formatter.

impl Eq for CheckComparisonOp

impl PartialEq for CheckComparisonOp

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