+
+ // 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 Code = 2
+
+ // InvalidArgument indicates client specified an invalid argument.
+ // Note that this differs from FailedPrecondition. It indicates arguments
+ // that are problematic regardless of the state of the system
+ // (e.g., a malformed file name).
+ InvalidArgument Code = 3
+
+ // DeadlineExceeded means operation expired before completion.
+ // 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.
+ DeadlineExceeded Code = 4
+
+ // NotFound means some requested entity (e.g., file or directory) was
+ // not found.
+ NotFound Code = 5
+
+ // AlreadyExists means an attempt to create an entity failed because one
+ // already exists.
+ AlreadyExists Code = 6
+
+ // PermissionDenied indicates the caller does not have permission to
+ // execute the specified operation. It must not be used for rejections
+ // caused by exhausting some resource (use ResourceExhausted
+ // instead for those errors). It must not be
+ // used if the caller cannot be identified (use Unauthenticated
+ // instead for those errors).
+ PermissionDenied Code = 7
+
+ // ResourceExhausted indicates some resource has been exhausted, perhaps
+ // a per-user quota, or perhaps the entire file system is out of space.
+ ResourceExhausted Code = 8
+
+ // FailedPrecondition indicates 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 FailedPrecondition, 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 FailedPrecondition 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, FailedPrecondition
+ // should be returned since the client should not retry unless
+ // they have first fixed up the directory by deleting files from it.
+ // (d) Use FailedPrecondition 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.
+ FailedPrecondition Code = 9
+
+ // Aborted indicates the operation was aborted, typically due to a
+ // concurrency issue like sequencer check failures, transaction aborts,
+ // etc.

+ // See litmus test above for deciding between FailedPrecondition,
+ // Aborted, and Unavailable.
+ Aborted Code = 10
+
+ // OutOfRange means operation was attempted past the valid range.
+ // E.g., seeking or reading past end of file.
+ //
+ // Unlike InvalidArgument, this error indicates a problem that may
+ // be fixed if the system state changes. For example, a 32-bit file
+ // system will generate InvalidArgument if asked to read at an
+ // offset that is not in the range [0,2^32-1], but it will generate
+ // OutOfRange if asked to read from an offset past the current
+ // file size.
+ //
+ // There is a fair bit of overlap between FailedPrecondition and
+ // OutOfRange. We recommend using OutOfRange (the more specific
+ // error) when it applies so that callers who are iterating through
+ // a space can easily look for an OutOfRange error to detect when
+ // they are done.

+ // Unimplemented indicates operation is not implemented or not
+ // supported/enabled in this service.

+ // system has been broken. If you see one of these errors,

+ // by retrying with a backoff.
