Trait Implementations

impl Clone for QueryFirstIntrospection

fn clone(&self) -> QueryFirstIntrospection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryFirstIntrospection

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

Formats the value using the given formatter.

impl Hash for QueryFirstIntrospection

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Introspect for QueryFirstIntrospection

type Output = Option<Content>

The kind of output the introspection produces. This is what should stabilize.

fn introspect( &self, _: &mut Engine<'_>, introspector: Tracked<'_, dyn Introspector + '_>, ) -> Self::Output

Resolves the output value.

fn diagnose(&self, history: &History<'_, Self::Output>) -> SourceDiagnostic

Produces a diagnostic for non-convergence given the history of its output values.

impl PartialEq for QueryFirstIntrospection

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