Implementations

pub const fn as_str(self) -> &'static str

Canonical label.

pub fn from_graphql_key(value: &str) -> Option<Self>

Maps the adapter’s standard GraphQL filter key to a canonical operator.

Trait Implementations

impl Clone for QueryComparisonOperator

fn clone(&self) -> QueryComparisonOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryComparisonOperator

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

Formats the value using the given formatter.

impl PartialEq for QueryComparisonOperator

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