Enum TransportMode 

pub enum TransportMode {
    Netstack,
    Tun(TunConfig),
}

How the node’s application overlay data path is realized.

Defaults to Netstack, the userspace smoltcp netstack that needs no privileges and is the right choice for the fork’s primary deployment (a privacy proxy / cloud exit node running unprivileged in a container). Tun instead hands the node’s overlay packets to a real kernel TUN interface, for embedders that want the host OS networking stack (routes, sockets, DNS) to see the tailnet directly — closer to tailscaled’s model than to Go tsnet’s in-process netstack.

Like the other dataplane fields this is not read inside ts_control: it is carried for transport only and converted to a ts_transport_tun config by the runtime at the ts_runtime boundary (ts_control must not depend on ts_transport_tun). The mode governs only the application data path; it never changes the exit-node / forwarder egress path, which stays its own IPv4-only userspace netstack regardless.

Variants

Netstack

Userspace smoltcp netstack (default). No privileges required.

Tun(TunConfig)

Real kernel TUN interface. Requires privileges (root / CAP_NET_ADMIN on Linux) and a platform that supports TUN (Linux /dev/net/tun, macOS utun).

Trait Implementations

impl Clone for TransportMode

fn clone(&self) -> TransportMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransportMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for TransportMode

fn default() -> TransportMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransportMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<TransportMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TransportMode

impl PartialEq for TransportMode

fn eq(&self, other: &TransportMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TransportMode

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
