Trait Implementations

impl Clone for Sum

fn clone(&self) -> Sum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sum

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

Formats the value using the given formatter.

impl Evaluate for Sum

type Output = f64

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

Evaluates the thing.

impl Kind for Sum

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 Sum

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

Serialize this value into the given Serde serializer.
