Types ¶

type Cache ¶

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

Cache used to determine rule keys

type Entry ¶

type Entry struct {
	Name string `json:"name"`
	Hash string `json:"hash"`
}

Entry carries the name and hash for one item within a Key

type Error ¶

type Error string

Error is used to handle cache misses and the like

func (Error) Error ¶

func (e Error) Error() string

	Native      bool     `json:"native,omitempty"`
	// contains filtered or unexported fields
}

Key contains information used to build a key
