CANCELLED = 1 """ Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error. """ UNKNOWN = 2 """ Client specified an invalid argument. Note that this differs from FAILED_PRECONDITION. INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name). """ INVALID_ARGUMENT = 3 """ Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire. """ DEADLINE_EXCEEDED = 4 """ Some requested entity (e.g., file or directory) was not found. For privacy reasons, this code *may* be returned when the client does not have the access right to the entity. """ NOT_FOUND = 5 """ Some entity that we attempted to create (e.g., file or directory) already exists. """ ALREADY_EXISTS = 6 """ The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller can not be identified (use UNAUTHENTICATED instead for those errors). """ PERMISSION_DENIED = 7 """ Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space. """ RESOURCE_EXHAUSTED = 8 """ Operation was rejected because the system is not in a state required for the operation's execution. For example, directory to be deleted may be non-empty, an rmdir operation is applied to a non-directory, etc. A litmus test that may help a service implementor in deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher-level (e.g., restarting a read-modify-write sequence). (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. E.g., if an "rmdir" fails because the directory is non-empty, FAILED_PRECONDITION should be returned since the client should not retry unless they have first fixed up the directory by deleting files from it. (d) Use FAILED_PRECONDITION if the client performs conditional REST Get/Update/Delete on a resource and the resource on the server does not match the condition. E.g., conflicting read-modify-write on the same resource. """ FAILED_PRECONDITION = 9 """ The operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc. See litmus test above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE. """ ABORTED = 10 """ Operation tried to iterate past the valid input range. E.g., seeking or reading past end of file. Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size. There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done. """ OUT_OF_RANGE = 11 # Operation is not implemented or not supported/enabled in this service. UNIMPLEMENTED = 12 """ Internal errors. Means some invariant expected by the underlying system has been broken. If you see one of these errors, something is very broken. """ INTERNAL = 13 """ The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff. See litmus test above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE.

""" UNAUTHENTICATED = 16 """ An extra enum entry to prevent people from writing code that fails to compile when a new code is added. Nobody should ever reference this enumeration entry. In particular, if you write C++ code that switches on this enumeration, add a default: case instead of a case that mentions this enumeration entry.
