The state a netmap is accumulated into.

Fields

peers: PeerTable<PEERS>

peers_truncated: bool

The control map named more peers than this target retains, or named a peer whose addresses or allowed IPs exceed the per-peer bounds.

Selection is deterministic and independent of server order: a full table keeps the highest-ranked non-self records (online first, then the lowest node id), skipping oversized records. With the alloc feature the table is full only at PEERS or when the allocator refuses to grow it. This lets memory-constrained targets remain connected to control instead of rejecting the entire map.

derp: DerpMap

dns: DnsConfig

The tailnet’s DNS configuration, minus the unbounded Routes map.

node_key: Option<NodePublic>

This node’s own record, once the server has sent one.

disco_key: Option<DiscoPublic>

addresses: Vec<Cidr, { crate::netmap::MAX_ADDRESSES }>

primary_routes: Vec<Cidr, { crate::netmap::MAX_PRIMARY_ROUTES }>

Routes this control plane has approved for this node.

home_derp: u16

Preferred relay for this node.

packet_filter: PacketPolicy

Staged packet-filter policy. No packet is forwarded until at least one syntactically valid policy update has been received.

responses: usize

How many complete MapResponses have been applied.

Implementations

impl<const PEERS: usize> Netmap<PEERS>

pub const fn new() -> Self

pub fn has_assigned_ipv4(&self) -> bool

pub fn ipv4_default_route_approved(&self) -> bool

Approval of 0.0.0.0/0 is independent of IPv6 uplink capability.

pub fn ipv6_default_route_approved(&self) -> bool

Only an explicitly approved ::/0 authorizes IPv6 exit forwarding.

pub fn default_routes_approved(&self) -> bool

Whether both exit-route families are approved. Family-specific packet paths must use the corresponding approval query instead.

Trait Implementations

impl<const PEERS: usize> Clone for Netmap<PEERS>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const PEERS: usize> Default for Netmap<PEERS>

fn default() -> Self

Returns the “default value” for a type.
