Types

type ContextEvaluator 

type ContextEvaluator *func(this InMemoryFlag, flatCtx openfeature.FlattenedContext) (any, openfeature.ProviderResolutionDetail)

ContextEvaluator is a callback to perform openfeature.EvaluationContext backed evaluations. This is a callback implemented by the flag definer.

type InMemoryEvent added in v1.14.0 

type InMemoryEvent struct {
	Value             float64
	Data              map[string]any
	ContextAttributes map[string]any
}

type InMemoryFlag 

type InMemoryFlag struct {
	Key              string
	State            State
	DefaultVariant   string
	Variants         map[string]any
	ContextEvaluator ContextEvaluator
}

InMemoryFlag is the feature flag representation accepted by InMemoryProvider
