Trait Implementations

impl Clone for QueryVariables

fn clone(&self) -> QueryVariables

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryVariables

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

Formats the value using the given formatter.

impl Default for QueryVariables

fn default() -> QueryVariables

Returns the “default value” for a type.

impl PartialEq for QueryVariables

fn eq(&self, other: &QueryVariables) -> 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 QueryVariableSet for QueryVariables

fn into_query_variables(self) -> QueryVariables
