Functions

func SeedFromDNS

func SeedFromDNS(dagParams *dagconfig.Params, customSeed string, reqServices appmessage.ServiceFlag, includeAllSubnetworks bool,
	subnetworkID *externalapi.DomainSubnetworkID, lookupFn LookupFunc, seedFn OnSeed)

SeedFromDNS uses DNS seeding to populate the address manager with peers.

func SeedFromGRPC

func SeedFromGRPC(dagParams *dagconfig.Params, customSeed string, reqServices appmessage.ServiceFlag, includeAllSubnetworks bool,
	subnetworkID *externalapi.DomainSubnetworkID, seedFn OnSeed)

SeedFromGRPC send gRPC request to get list of peers for a given host

Types

type LookupFunc

LookupFunc is the signature of the DNS lookup function.

type OnSeed

type OnSeed func(addrs []*appmessage.NetAddress)
