var DefaultPrototypeChooser = func(lnk ipld.Link, lnkCtx ipld.LinkContext) (ipld.NodePrototype, error) {
	if tlnkNd, ok := lnkCtx.LinkNode.(schema.TypedLinkNode); ok {
		return tlnkNd.LinkTargetNodePrototype(), nil
	}
	return basicnode.Prototype.Any, nil
}

DefaultPrototypeChooser supports choosing the prototype from the link and falling back to a basicnode.Any builder

Types

type FetcherConfig

type FetcherConfig struct {
	NodeReifier      ipld.NodeReifier
	PrototypeChooser traversal.LinkTargetNodePrototypeChooser
	// contains filtered or unexported fields
}

FetcherConfig defines a configuration object from which Fetcher instances are constructed

Deprecated: use github.com/ipfs/boxo/fetcher/impl/blockservice.FetcherConfig

func NewFetcherConfig

func NewFetcherConfig(blockService blockservice.BlockService) FetcherConfig

NewFetcherConfig creates a FetchConfig from which session may be created and nodes retrieved.

Deprecated: use github.com/ipfs/boxo/fetcher/impl/blockservice.NewFetcherConfig

func (FetcherConfig) FetcherWithSession

func (fc FetcherConfig) FetcherWithSession(ctx context.Context, s *blockservice.Session) fetcher.Fetcher

func (FetcherConfig) NewSession

func (fc FetcherConfig) NewSession(ctx context.Context) fetcher.Fetcher

NewSession creates a session from which nodes may be retrieved. The session ends when the provided context is canceled.

func (FetcherConfig) WithReifier

func (fc FetcherConfig) WithReifier(nr ipld.NodeReifier) fetcher.Factory

WithReifier derives a different fetcher factory from the same source but with a chosen NodeReifier for pathing semantics.
