Functions

func InitializeKeyspace

func InitializeKeyspace(n *core.IpfsNode, key ci.PrivKey) error

InitializeKeyspace将给定密钥的IPN记录设置为 指向空目录。

func Mount

func Mount(ipfs *core.IpfsNode, ipnsmp, ipfsmp string) (mount.Mount, error)

mount在给定位置安装IPN，并返回mount.mount实例。

Types

type Directory

type Directory struct {
	// contains filtered or unexported fields
}

目录是对mfs目录的包装，以满足fuse fs接口

func (*Directory) Attr

func (d *Directory) Attr(ctx context.Context, a *fuse.Attr) error

ATTR返回给定节点的属性。

func (*Directory) Create

func (dir *Directory) Create(ctx context.Context, req *fuse.CreateRequest, resp *fuse.CreateResponse) (fs.Node, fs.Handle, error)

func (*Directory) Lookup

func (s *Directory) Lookup(ctx context.Context, name string) (fs.Node, error)

查找在此节点下执行查找。

func (*Directory) Mkdir

func (dir *Directory) Mkdir(ctx context.Context, req *fuse.MkdirRequest) (fs.Node, error)

func (*Directory) ReadDirAll

func (dir *Directory) ReadDirAll(ctx context.Context) ([]fuse.Dirent, error)

readdirall将链接结构作为目录项读取

func (*Directory) Remove

func (dir *Directory) Remove(ctx context.Context, req *fuse.RemoveRequest) error

func (*Directory) Rename

func (dir *Directory) Rename(ctx context.Context, req *fuse.RenameRequest, newDir fs.Node) error

rename实现noderenamer
