Types ¶
type LabelKey ¶
type LabelKey struct {
Key string `json:"key" binding:"required"`
Labels []string `json:"labels" binding:"required"`
}
LabelKey is the decoration key.
type LabelStrategy ¶
type LabelStrategy interface {
ReloadConfig(cfg *config.KeyVisualConfig)
NewLabeler() Labeler
}
LabelStrategy requires cross-border determination and key decoration scheme. It supports dynamic reload configuration and generation of an actuator.
func NaiveLabelStrategy ¶
func NaiveLabelStrategy() LabelStrategy
NaiveLabelStrategy is one of the simplest LabelStrategy.
func SeparatorLabelStrategy ¶
func SeparatorLabelStrategy(cfg *config.KeyVisualConfig) LabelStrategy
SeparatorLabelStrategy implements the LabelStrategy interface. It obtains label information after splitting the key.
type Labeler ¶
type Labeler interface {
// CrossBorder determines whether two keys not belong to the same logical range.
CrossBorder(startKey, endKey string) bool
// Label returns the Label information of the keys.
Label(keys []string) []LabelKey
}
Labeler is an executor of LabelStrategy, and its functions should not be called concurrently.
