Functions

func ToFloat64

func ToFloat64(val interface{}) (float64, error)

ToFloat64 attempts to convert an interface{} value to a float64. It supports inputs of type float64 or string (which can be parsed as float64). Returns a float64 and nil error on success, or 0 and an error on failure.

Types

type Allocation

type Allocation struct {
	PercentExposure float32     `json:"percentExposure"`
	Variations      []Variation `json:"variations"`
}

type AssignmentEvent

type AssignmentEvent struct {
	Experiment        string     `json:"experiment"`
	FeatureFlag       string     `json:"featureFlag"`
	Allocation        string     `json:"allocation"`
	Variation         Value      `json:"variation"`
	Subject           string     `json:"subject"`
	Timestamp         string     `json:"timestamp"`
	SubjectAttributes dictionary `json:"subjectAttributes,omitempty"`
}

type AssignmentLogger

type AssignmentLogger struct {
}

func (*AssignmentLogger) LogAssignment

func (al *AssignmentLogger) LogAssignment(event AssignmentEvent)

type Config

type Config struct {
	BaseUrl          string
	ApiKey           string
	AssignmentLogger IAssignmentLogger
}

type EppoClient

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

Client for eppo.cloud. Instance of this struct will be created on calling InitClient. EppoClient will then immediately start polling experiments data from Eppo.

func InitClient

func InitClient(config Config) *EppoClient

InitClient is required to start polling of experiments configurations and create an instance of EppoClient, which could be used to get assignments information.

func (*EppoClient) GetAssignment

func (ec *EppoClient) GetAssignment(subjectKey string, flagKey string, subjectAttributes dictionary) (string, error)

GetAssignment is maintained for backwards capability. It will return a string value for the assignment.

func (*EppoClient) GetBoolAssignment

func (ec *EppoClient) GetBoolAssignment(subjectKey string, flagKey string, subjectAttributes dictionary) (bool, error)

func (*EppoClient) GetJSONStringAssignment

func (ec *EppoClient) GetJSONStringAssignment(subjectKey string, flagKey string, subjectAttributes dictionary) (string, error)

func (*EppoClient) GetNumericAssignment

func (ec *EppoClient) GetNumericAssignment(subjectKey string, flagKey string, subjectAttributes dictionary) (float64, error)

func (*EppoClient) GetStringAssignment

func (ec *EppoClient) GetStringAssignment(subjectKey string, flagKey string, subjectAttributes dictionary) (string, error)

type IAssignmentLogger

type IAssignmentLogger interface {
	LogAssignment(event AssignmentEvent)
}

func NewAssignmentLogger

func NewAssignmentLogger() IAssignmentLogger

type SDKParams

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

type Value

type Value struct {
	ValueType    ValueType `json:"valueType"`
	BoolValue    bool      `json:"boolValue,omitempty"`
	NumericValue float64   `json:"numericValue,omitempty"`
	StringValue  string    `json:"stringValue,omitempty"`
}

func Bool

func Bool(value bool) Value

func Null

func Null() Value

func Numeric

func Numeric(value float64) Value

func (Value) MarshalJSON

func (v Value) MarshalJSON() ([]byte, error)

func (*Value) UnmarshalJSON

func (v *Value) UnmarshalJSON(data []byte) error

type ValueType

type ValueType int

const (
	NullType    ValueType = iota
	BoolType    ValueType = iota
	NumericType ValueType = iota
	StringType  ValueType = iota
)

type Variation

type Variation struct {
	Name       string     `json:"name"`
	Value      Value      `json:"typedValue"`
	ShardRange shardRange `json:"shardRange"`
}
