const ( // OK is returned on success. OK int = 0 // Canceled indicates the operation was canceled (typically by the caller). // // The gRPC framework will generate this error code when cancellation // is requested. Canceled int = 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. // // The gRPC framework will generate this error code in the above two // mentioned cases. Unknown int = 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). // // This error code will not be generated by the gRPC framework. InvalidArgument int = 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. // // The gRPC framework will generate this error code when the deadline is // exceeded. DeadlineExceeded int = 4 // NotFound means some requested entity (e.g., file or directory) was // not found. // // This error code will not be generated by the gRPC framework. NotFound int = 5 // AlreadyExists means an attempt to create an entity failed because one // already exists. // // This error code will not be generated by the gRPC framework. AlreadyExists int = 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). // // This error code will not be generated by the gRPC core framework, // but expect authentication middleware to use it. PermissionDenied int = 7 // ResourceExhausted indicates some resource has been exhausted, perhaps // a per-user quota, or perhaps the entire file system is out of space. // // This error code will be generated by the gRPC framework in // out-of-memory and server overload situations, or when a message is // larger than the configured maximum size. ResourceExhausted int = 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. // // This error code will not be generated by the gRPC framework. FailedPrecondition int = 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. // // This error code will not be generated by the gRPC framework. Aborted int = 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. // // This error code will not be generated by the gRPC framework. OutOfRange int = 11 // Unimplemented indicates operation is not implemented or not // supported/enabled in this service. // // This error code will be generated by the gRPC framework. Most // commonly, you will see this error code when a method implementation // is missing on the server. It can also be generated for unknown // compression algorithms or a disagreement as to whether an RPC should // be streaming. Unimplemented int = 12 // Internal errors. Means some invariants expected by underlying // system has been broken. If you see one of these errors, // something is very broken. // // This error code will be generated by the gRPC framework in several // internal error conditions. Internal int = 13 // This is a most likely a transient condition and may be corrected // by retrying with a backoff. Note that it is not always safe to retry // non-idempotent operations. // // See litmus test above for deciding between FailedPrecondition, // Aborted, and Unavailable. // // This error code will be generated by the gRPC framework during // abrupt shutdown of a server process or network connection. Unavailable int = 14 // DataLoss indicates unrecoverable data loss or corruption. // // This error code will not be generated by the gRPC framework. DataLoss int = 15 // Unauthenticated indicates the request does not have valid // authentication credentials for the operation. // // The gRPC framework will generate this error code when the // authentication metadata is invalid or a Credentials callback fails, // but also expect authentication middleware to generate it. Unauthenticated int = 16 )
