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:

$ godoc

type BuildCfg = node.BuildCfg // Alias for compatibility until we properly refactor the constructor interface

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

func NewNode

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

func (n *IpfsNode) Close() error

Close calls Close() on the App object

func (*IpfsNode) Context

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.
