Functions

func MustGetStringMap

func MustGetStringMap(getter Getter, key string) map[string]interface{}

Types

type Getter

type Getter interface {
	// GetStringMap expected to return nil if key does not exist
	GetStringMap(key string) (map[string]interface{}, error)
}

func FromEnv

func FromEnv() (Getter, error)

func MergeGetters

func MergeGetters(backends ...Getter) Getter

func MustFromEnv

func MustFromEnv() Getter

func NewViperFile

func NewViperFile(fn string) Getter

type GetterFunc

type GetterFunc func(key string) (map[string]interface{}, error)

The GetterFunc type is an adapter to allow the use of ordinary functions as Getter. If f is a function with the appropriate signature, GetterFunc(f) is a Getter that calls f.

func (GetterFunc) GetStringMap

func (f GetterFunc) GetStringMap(key string) (map[string]interface{}, error)

GetStringMap calls f(key).
