## Cases

| Name | Type | Summary |
| --- | --- | --- |
| case assetsNotFound | assetsNotFound | The site was found but has no assets to localize against: either none of therequested asset ids are in it, or the matching assets were not localizable. |
| case authFailure | authFailure | The API gateway rejected the request due to an authentication or authorization failure. |
| case badCameraAngle | badCameraAngle | The frame was rejected because the camera is pointing at the ground or sky (no horizon crossing). |
| case badNetworkConnection | badNetworkConnection | The device cannot connect to the server. |
| case badTracking | badTracking | The frame was rejected because tracking state is not normal. |
| case deviceUpsideDown | deviceUpsideDown | The frame was rejected because the device was held upside down. |
| case imageTooBlurry | imageTooBlurry | The frame was flagged because the image was too blurry or featureless to localize well.Advisory: the frame is still sent; use this to coach the user, not to explain a drop. |
| case internalClient | internalClient | The server response could not be parsed by the client. |
| case internalServer | internalServer | The server encountered an internal error while processing the request. |
| case localizationFailed | localizationFailed | The server processed the request but localization failed. |
| case noMapFound | noMapFound | The server could not find a map near the request GPS location. |
| case none | none | No error has occurred. |
| case noValidPrior | noValidPrior | The frame was rejected before dispatch because no valid geolocation prior was available(the GPS reading was NaN or a placeholder and no other valid prior could be substituted). |
| case permissionDenied | permissionDenied | The server denied permission for the request. |
| case quotaExceeded | quotaExceeded | The API gateway rejected the request because the account or project quota was exceeded (HTTP 429). |
| case requestsLimitExceeded | requestsLimitExceeded | The request rate limit has been exceeded. |
| case siteNotFound | siteNotFound | The requested site does not exist or is not accessible to this caller. |
| case unknown | unknown | An unknown error occurred. |

## Operators

| Name | Type | Summary |
| --- | --- | --- |
| static func != | Bool | Returns a Boolean value indicating whether two values are not equal.Inequality is the inverse of equality. For any values `a` and `b`, `a != b`implies that `a == b` is `false`.This is the default implementation of the not-equal-to operator (`!=`)for any type that conforms to `Equatable`. |
