Types

type FSSource 

type FSSource interface {
	fmt.Stringer

	// Get builds a single instance of an fs.FS
	Get() (fs.FS, error)

	// Subscribe feeds implementations of fs.FS onto the provided channel.
	// It should block until the provided context is cancelled (it will be called in a goroutine).
	// It should close the provided channel before it returns.
	Subscribe(context.Context, chan<- fs.FS)
}

FSSource produces implementations of fs.FS. A single FS can be produced via Get or a channel may be provided to Subscribe in order to received new instances when new state becomes available.

type FliptIndex 

type FliptIndex struct {
	Version string   `yaml:"version,omitempty"`
	Include []string `yaml:"include,omitempty"`
	Exclude []string `yaml:"exclude,omitempty"`
}

FliptIndex represents the structure of a well-known file ".flipt.yml" at the root of an FS.

type Store 

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

Store is an implementation of storage.Store backed by an FSSource. The store subscribes to the source for instances of fs.FS with new contents. When a new fs is received the contents is fetched and built into a snapshot of Flipt feature flag state.

func NewStore 

func NewStore(logger *zap.Logger, source FSSource) (*Store, error)

NewStore constructs and configure a Store. The store creates a background goroutine which feeds a channel of fs.FS.

func (*Store) Close 

func (l *Store) Close() error

Close cancels the polling routine and waits for the routine to return.
