[−][src]Struct evaluator::DummyEval

pub struct DummyEval<Out> { /* fields omitted */ }

Implements dummy evaluation of clonable and non-clonable types: every time the eval() method is called, a fixed value is returned.

Trait Implementations

impl<Out> Evaluator for DummyEval<Out> where
    Out: Clone, [src]

type Output = Out

The type that the evaluator evaluates to.

fn eval(&mut self) -> Self::Output[src]

Evaluates and returns the result. This includes the overhead of cloning the value, because the fixed value must be preserved.

Because caching evaluators, as their name suggests, store the cached value inside themselves, a mutable borrow of self is required.

Panics

May panic only if cloning of the inner value panics.

impl<Out> From<Out> for DummyEval<Out>[src]

fn from(value: Out) -> Self[src]

Constructs the evaluator from the specified dummy value.
