Package core implements the IpfsNode object and related methods.

Packages underneath core/ provide a (relatively) stable, low-level API to carry out most IPFS-related tasks. For more details on the other interfaces and how core/... fits into the bigger IPFS picture, see:

IpfsNode is IPFS Core module. It represents an IPFS instance.

func NewNode added in v0.3.8

func NewNode(ctx context.Context, cfg *BuildCfg) (*IpfsNode, error)

NewNode constructs and returns an IpfsNode using the given cfg.

func (*IpfsNode) Bootstrap

func (n *IpfsNode) Bootstrap(cfg bootstrap.BootstrapConfig) error

Bootstrap will set and call the IpfsNodes bootstrap function.

func (*IpfsNode) Close added in v0.3.6

func (n *IpfsNode) Close() error

Close calls Close() on the App object

func (*IpfsNode) Context added in v0.3.6

func (n *IpfsNode) Context() context.Context

Context returns the IpfsNode context

type Mounts

type Mounts struct {
	Ipfs mount.Mount
	Ipns mount.Mount

Mounts defines what the node's mount state is. This should perhaps be moved to the daemon or mount. It's here because it needs to be accessible across daemon requests.
