	// KindUnknown error. For example when handling errors raised by APIs that do not
	// return enough error information.
	KindUnknown Kind = "unknown"

	// KindInvalidArgument indicates client specified an invalid argument. It
	// indicates arguments that are problematic regardless of the state of the
	// system (i.e. a malformed file name, required argument, number out of range,
	// etc.).
	KindInvalidArgument Kind = "invalid_argument"

	// KindDeadlineExceeded 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 (timeout).
	KindDeadlineExceeded Kind = "deadline_exceeded"

	// KindNotFound means some requested entity was not found.
	KindNotFound Kind = "not_found"

	// AlreadyExists means an attempt to create an entity failed because one
	// already exists.
	KindAlreadyExists Kind = "already_exists"

	// KindPermissionDenied indicates the caller does not have permission to execute
	// the specified operation. It must not be used if the caller cannot be
	// identified (Unauthenticated).
	KindPermissionDenied Kind = "permission_denied"

	// KindUnauthenticated indicates the request does not have valid authentication
	// credentials for the operation.

	// KindResourceExhausted indicates some resource has been exhausted, perhaps a
	// per-user quota, or perhaps the entire file system is out of space.
	KindResourceExhausted Kind = "resource_exhausted"

	// KindFailedPrecondition indicates operation was rejected because the system is
	// not in a state required for the operation's execution. For example, doing
	// an rmdir operation on a directory that is non-empty, or on a non-directory
	// object, or when having conflicting read-modify-write on the same resource.
	KindFailedPrecondition Kind = "failed_precondition"

	// KindAborted indicates the operation was aborted, typically due to a concurrency
	// issue like sequencer check failures, transaction aborts, etc.
	KindAborted Kind = "aborted"

	// KindOutOfRange means operation was attempted past the valid range. For example,
	// seeking or reading past end of a paginated collection.
	//
	// Unlike InvalidArgument, this error indicates a problem that may be fixed if
	// the system state changes (i.e. adding more items to the collection).
	//
	// 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.

	// KindInternal errors. When some invariants expected by the underlying system
	// have been broken. In other words, something bad happened in the library or
	// backend service. Do not confuse with HTTP Internal Server Error; an
	// Internal error could also happen on the client code, i.e. when parsing a
	// server response.

	// KindUnavailable indicates the service is currently unavailable. This is a most
	// likely a transient condition and may be corrected by retrying with a
	// backoff.
