Trait Implementations

impl Clone for Negation

fn clone(&self) -> Negation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Negation

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

Formats the value using the given formatter.

impl Evaluate for Negation

type Output = f64

fn evaluate(&self, args: &EvaluationArgs<'_>) -> f64

Evaluates the thing.

impl Kind for Negation

fn collect(&self, exprs: &mut Vec<usize>)

fn is_trivial(&self) -> bool

Trivial expressions are ones that don’t require any calculations being made. Trivial expressions should not be cached, as it is much faster to evaluate them than to get their caches.

fn evaluate_weights(&self) -> Weights

Evaluates weights.

impl Serialize for Negation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
