NewClient returns new Client for the given apiServer and the given ac.

func (*Client) GetAPIResponse

func (c *Client) GetAPIResponse(path string) ([]byte, error)

GetAPIResponse returns response for the given absolute path.

type ConfigMap

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

ConfigMap is a map for storing discovery api configs.

It automatically removes old configs which weren't accessed recently.

func NewConfigMap

func NewConfigMap() *ConfigMap

NewConfigMap creates ConfigMap

func (*ConfigMap) Get

func (cm *ConfigMap) Get(key interface{}, newConfig func() (interface{}, error)) (interface{}, error)

Get returns config for the given key.

Key must be a pointer.

It creates new config map with newConfig() call if cm doesn't contain config under the given key.

type SortedLabels

type SortedLabels []prompbmarshal.Label

SortedLabels represents sorted labels.

func GetSortedLabels

func GetSortedLabels(m map[string]string) SortedLabels

GetSortedLabels returns SortedLabels built from m.

func (*SortedLabels) UnmarshalJSON

func (sls *SortedLabels) UnmarshalJSON(data []byte) error

UnmarshalJSON unmarshals JSON from data.
