Struct TestEvaluator 

pub struct TestEvaluator { /* private fields */ }

A test evaluator that allows setting features for testing purposes.

Implementations

impl TestEvaluator

pub fn new() -> TestEvaluator

Create a new TestEvaluator.

pub fn set_feature<T: TestFeature>(&self, feature: &str, enabled: T)

Set the state of a feature.

The feature can be set to any value that implements TestFeature, which allows for complex logic to determine if a feature is enabled. TestFeature is automatically implemented for bool, Option<bool> and Fn(&Context) -> impl TestFeature.

pub fn clear_feature(&self, feature: &str)

Unset a feature.

Trait Implementations

impl Default for TestEvaluator

fn default() -> Self

Returns the “default value” for a type.

impl Evaluator for TestEvaluator

fn is_enabled(&self, feature: &str, _context: &Context) -> Option<bool>

Checks if a feature is enabled in the given context.

fn on_new_context(&self, context: ContextRef<'_>, fields: Fields<'_>)

Called when a new context is created.

fn on_registration(&self)

Called when the evaluator is registered.

fn on_close_context(&self, context: ContextRef<'_>)

Called when a context is closed.

fn into_ref(self) -> EvaluatorRef

where Self: Sized + 'static,

Converts the evaluator into an EvaluatorRef.
