Types

type DirectoryNodeProto 

type DirectoryNodeProto struct {
	// Children of this directory. Note that paths are relative, so if "/foo/bar"
	// has a child "baz", that means that there is a file at "/foo/bar/baz".
	//
	// 'Children' is ordered alphabetically, to quickly check if a new file is
	// overwriting an existing one.
	Children             []string    `protobuf:"bytes,3,rep,name=children,proto3" json:"children,omitempty"`
	Header               *pfs.Object `protobuf:"bytes,4,opt,name=header,proto3" json:"header,omitempty"`
	Footer               *pfs.Object `protobuf:"bytes,5,opt,name=footer,proto3" json:"footer,omitempty"`

	XXX_unrecognized     []byte      `json:"-"`
	XXX_sizecache        int32       `json:"-"`
}
