Types

type ConfigResponseEvaluator

type ConfigResponseEvaluator struct {
	// contains filtered or unexported fields
}

ConfigResponseEvaluator wraps an Evaluator to work with ConfigResponse objects. It implements the quonfig.configEvaluator interface (unexported, matched by method).

func NewConfigResponseEvaluator

func NewConfigResponseEvaluator(configStore ConfigStoreGetter) *ConfigResponseEvaluator

NewConfigResponseEvaluator creates a new ConfigResponseEvaluator. The configStore is used for segment resolution during evaluation.

func (*ConfigResponseEvaluator) EvaluateConfigResponse

func (e *ConfigResponseEvaluator) EvaluateConfigResponse(cfg *quonfig.ConfigResponse, envID string, ctx *quonfig.ContextSet) *quonfig.Value

EvaluateConfigResponse evaluates a ConfigResponse for the given environment and context. Returns the matched value (or nil if no match).

type ConfigStoreAdapter

type ConfigStoreAdapter struct {
	GetFn func(key string) (*quonfig.ConfigResponse, bool)
}

ConfigStoreAdapter adapts a function to the ConfigStoreGetter interface.

func (*ConfigStoreAdapter) GetConfig

func (a *ConfigStoreAdapter) GetConfig(key string) (*FullConfig, bool)

type ConfigStoreGetter

type ConfigStoreGetter interface {
	GetConfig(key string) (*FullConfig, bool)
}

ConfigStoreGetter retrieves configs by key.

type ContextValueGetter

type ContextValueGetter = evalcore.ContextValueGetter

ContextValueGetter is re-exported from the shared evalcore package.

type EmptyContext

type EmptyContext = evalcore.EmptyContext

EmptyContext is re-exported from the shared evalcore package.

type EvalMatch

type EvalMatch struct {
	IsMatch            bool
	Value              *quonfig.Value
	RuleIndex          int
	WeightedValueIndex int
}

EvalMatch is the result of evaluating a config against a context.

type Evaluator

type Evaluator struct {
	// contains filtered or unexported fields
}

Evaluator is the main evaluation engine. It delegates to the shared evalcore package.

func NewEvaluator

func NewEvaluator(configStore ConfigStoreGetter) *Evaluator

NewEvaluator creates a new Evaluator.

func NewEvaluatorWithSeed

func NewEvaluatorWithSeed(configStore ConfigStoreGetter, seed int64) *Evaluator

NewEvaluatorWithSeed creates a new Evaluator with a fixed random seed (for testing).

func NewEvaluatorWithTimeSeed

func NewEvaluatorWithTimeSeed(configStore ConfigStoreGetter) *Evaluator

NewEvaluatorWithTimeSeed creates a new Evaluator with a time-based seed.

func (*Evaluator) EvaluateConfig

func (e *Evaluator) EvaluateConfig(cfg *FullConfig, envID string, ctx ContextValueGetter) *EvalMatch

EvaluateConfig evaluates a config for the given environment and context.

type FullConfig

type FullConfig struct {
	ID              string                `json:"id"`
	Key             string                `json:"key"`
	Type            quonfig.ConfigType    `json:"type"`
	ValueType       quonfig.ValueType     `json:"valueType"`
	SendToClientSDK bool                  `json:"sendToClientSdk"`
	Default         quonfig.RuleSet       `json:"default"`
	Environments    []quonfig.Environment `json:"environments,omitempty"`
}

FullConfig is a config with all environments, matching the raw JSON format. This is used for evaluation where we need to look up configs by environment.

func ConfigResponseToFullConfig

func ConfigResponseToFullConfig(cr *quonfig.ConfigResponse) *FullConfig

ConfigResponseToFullConfig converts a ConfigResponse (with optional single environment) to a FullConfig (with environments array) for use with the evaluator.

func (*FullConfig) FindEnvironment

func (c *FullConfig) FindEnvironment(envID string) *quonfig.Environment

FindEnvironment returns the environment block matching the given environment ID, or nil.
