// The Resolver is how the webfinger service looks up a user or resource. The resolver
// must be provided by the developer using this package, as each webfinger
// service may be exposing a different set or users or resources or services.

// DummyUser allows us to return a dummy user to avoid user-enumeration via webfinger 404s. This
// can be done in the webfinger code itself but then it would be obvious which users are real
// and which are not real via differences in how the implementation works vs how
// the general webfinger code works. This does not match the webfinger specification
// but is an extra precaution. Returning a NotFound error here will
// keep the webfinger 404 behavior.

// IsNotFoundError returns true if the given error is a not found error.
