Constants

const (
	// OK 成功返回
	OK = codes.OK

	// CodeCanceled 表示操作已取消（通常由调用者取消）
	CodeCanceled = codes.Canceled

	// CodeUnknown 未知错误
	CodeUnknown = codes.Unknown

	// CodeInvalidArgument 客户端传递了一个无效的参数
	CodeInvalidArgument = codes.InvalidArgument

	// CodeDeadlineExceeded 表示操作在完成前过期。对于改变系统状态的操作，即使操作成功完成，也可能会返回此错误。
	// 例如，来自服务器的成功响应可能已延迟足够长的时间以使截止日期到期
	CodeDeadlineExceeded = codes.DeadlineExceeded

	// CodeNotFound 表示未找到某些请求的实体（例如文件或目录）
	CodeNotFound = codes.NotFound

	// CodeAlreadyExists 表示创建实体的尝试失败，因为实体已经存在
	CodeAlreadyExists = codes.AlreadyExists

	// CodePermissionDenied 表示调用者没有执行指定操作的权限
	CodePermissionDenied = codes.PermissionDenied

	// CodeResourceExhausted 表示某些资源已用尽，可能是每个用户的配额，或者可能是整个文件系统空间不足
	CodeResourceExhausted = codes.ResourceExhausted

	// CodeFailedPrecondition 操作被拒绝，因为系统未处于操作执行所需的状态。
	// 例如，要删除的目录可能是非空的，rmdir 操作应用于非目录等
	CodeFailedPrecondition = codes.FailedPrecondition

	// CodeAborted 操作已取消，通常是由于并发问题，如排序器检查失败、事务中止
	CodeAborted = codes.Aborted

	// CodeOutRange 超出范围的操作
	CodeOutRange = codes.OutOfRange

	// CodeUnimplemented 未实现或不支持的操作
	CodeUnimplemented = codes.Unimplemented

	// CodeInternal 系统内部错误
	CodeInternal = codes.Internal

	// CodeUnavailable 表示该服务当前不可用。这很可能是一种瞬态情况，可以通过回退重试来纠正。
	// 请注意，重试非幂等操作是不安全的
	CodeUnavailable = codes.Unavailable

	// CodeDataLoss 表示不可恢复的数据丢失或损坏
	CodeDataLoss = codes.DataLoss

	// CodeUnauthenticated 表示请求没有用于操作的有效身份验证凭据
	CodeUnauthenticated = codes.Unauthenticated
