Overview

Package ipnstate captures the entire state of the Tailscale network.

It's a leaf package so ipn, wgengine, and magicsock can all depend on it.

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

func (*StatusBuilder) AddPeer 

func (sb *StatusBuilder) AddPeer(peer key.NodePublic, st *PeerStatus)

func (sb *StatusBuilder) MutateStatus(f func(*Status))

MutateStatus calls f with the status to mutate.

It may not assume other fields of status are already populated, and may not retain or write to the Status after f returns.

	// MagicDNSSuffix is the network's MagicDNS suffix for nodes
	// in the network such as "userfoo.tailscale.net".
	// There are no surrounding dots.
	// MagicDNSSuffix should be populated regardless of whether a domain
	// has MagicDNS enabled.
