// OK is returned on success.
OK Code = 0
// Canceled indicates the operation was canceled (typically by the caller).
Canceled Code = 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 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.
OutOfRange Code = 11
// Unimplemented indicates operation is not implemented or not
// supported/enabled in this service.
Unimplemented Code = 12
// Internal errors. Means some invariants expected by underlying
// system has been broken. If you see one of these errors,
// something is very broken.
Internal Code = 13
// Unavailable indicates the service is currently unavailable.
// 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.
Unavailable Code = 14
// DataLoss indicates unrecoverable data loss or corruption.
