Functions

func InitializeKeyspace

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

InitializeKeyspace sets the ipns record for the given key to point to an empty directory.

func Mount

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

Mount mounts ipns at a given location, and returns a mount.Mount instance.

Types

type Directory

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

Directory is wrapper over an mfs directory to satisfy the fuse fs interface

func (*Directory) Attr

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

Attr returns the attributes of a given node.

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)

Lookup performs a lookup under this node.
