type Backend

	// The backends must check the operation type and handle appropriately.
	HandleRequest(context.Context, *Request) (*Response, error)

	// SpecialPaths is a list of paths that are special in some way.
	// See PathType for the types of special paths. The key is the type
	// of the special path, and the value is a list of paths for this type.
	// This is not a regular expression but is an exact match. If the path
	// ends in '*' then it is a prefix-based match. The '*' can only appear
	// at the end.
	SpecialPaths() *Paths

	// System provides an interface to access certain system configuration
	// information, such as globally configured default and max lease TTLs.
	System() SystemView

	// Logger provides an interface to access the underlying logger. This
	// is useful when a struct embeds a Backend-implemented struct that
	// contains a private instance of logger.
	Logger() log.Logger

	// HandleExistenceCheck is used to handle a request and generate a response
	// indicating whether the given path exists or not; this is used to

	// Cleanup is invoked during an unmount of a backend to allow it to
	// handle any cleanup like connection closing or releasing of file handles.

	// configuration.
	Setup(context.Context, *BackendConfig) error

	// Type returns the BackendType for the particular backend

}

Backend interface must be implemented to be "mountable" at a given path. Requests flow through a router which has various mount points that flow to a logical backend. The logic of each backend is flexible, and this is what allows materialized keys to function. There can be specialized logical backends for various upstreams (Consul, PostgreSQL, MySQL, etc) that can interact with remote APIs to generate keys dynamically. This interface also allows for a "procfs" like interaction, as internal state can be exposed by acting like a logical backend and being mounted.

	// System provides a view into a subset of safe system information that
	// is useful for backends, such as the default/max lease TTLs
	System SystemView

	// BackendUUID is a unique identifier provided to this backend. It's useful
	// when a backend needs a consistent and unique string without using storage.
	BackendUUID string

	// Config is the opaque user configuration provided when mounting
	Config map[string]string
