	ErrCantCreateDatabase = errors.New("can't create the database")
	ErrorDatabaseNotFound = errors.New("database not found")

Functions ¶

Types ¶

type Factory ¶

type Factory func() (URLDataStore, error)

type Maintainable ¶

type Maintainable interface {
	Create() error
	Clear() error
	Maintain() error
}

This interface adds create/clear/maintain methods to the URLDataStore interface. URLDataStores may support these methods to create, clear, and maintain the store.

type Observable ¶ added in v0.6.5

type Observable interface {
	Stats() (any, error)
}

This interface is to expose a method to supply data to healthchecks.

type URLDataStore ¶

type URLDataStore interface {
	fetch.URLFetcher
	Save(*resource.WebPage) (uint64, error)
	Ping() error
	Delete(*nurl.URL) (bool, error)
}

This interface is the contract for storing and retrieving WebPage resources. It adds a Store() method to the fetch.URLFetcher interface. The fmt.Stringer interface is mainly to provide a way for the store to represent itself in log messages, e.g. a safe version of the DSN.
