func (c *Client) GetFileInfoByInode(ctx context.Context, auth eosclient.Authorization, inode uint64) (*eosclient.FileInfo, error)

GetFileInfoByInode returns the FileInfo by the given inode.

func (*Client) GetFileInfoByPath

func (c *Client) GetFileInfoByPath(ctx context.Context, auth eosclient.Authorization, path string) (*eosclient.FileInfo, error)

GetFileInfoByPath returns the FilInfo at the given path.

func (*Client) GetQuota
