}

Multiplexed control message.

Layout: control_type(1) + body (variable, depends on type).

Mesh-essential variants (IP lease, routing, liveness, identity) live here directly. Optional features such as user messaging are carried inside ControlFrame::PluginPayload so the daemon can be built without those plugins compiled in.

Variants

IpRequest

Request an address lease from a gateway.

Fields

requester_id: NodeId

Node requesting a mesh IP allocation.

IpAssign

Lease configuration returned by a gateway.

Fields

assigned_ip: [u8; 4]

Assigned mesh IPv4 address.

subnet_mask: u8

CIDR prefix length for the assigned subnet.

gateway_ip: [u8; 4]

Mesh IPv4 address of the serving gateway.

lease_seconds: u32

Lease duration in seconds.

Goodbye

Graceful disconnect notification.

Fields

departing_id: NodeId

Node that is departing.

reason: u8

Implementation-defined reason code.

Rekey

Request that the session be rekeyed.

Ping

Ping carrying an opaque nonce.

Fields

nonce: u64

Opaque value echoed by the corresponding pong.

Pong

Pong echoing a ping nonce.

Fields

nonce: u64

Opaque value copied from the ping request.

PeerInfo

Identity metadata exchanged once after the session is established so that peers can address each other by NodeId and end-to-end encrypt to the recipient’s static X25519 key.

Fields

x25519_pub: [u8; 32]

X25519 public key derived from the sender’s Ed25519 seed.

friendly_name: String

Sender’s friendly node name as configured locally (UTF-8, length-prefixed by u8 — capped at 255 bytes by the codec).

PluginPayload

Generic plugin-defined payload.

kind is an ASCII identifier (≤ 255 bytes) registered by a pim-plugin-style plugin (e.g. "messaging.msg"). body is plugin-private and opaque to the daemon — typically further encrypted/serialized according to the plugin’s own scheme.

Wire layout:

0x08
kind_len (u8, 1..=255)
kind     (kind_len bytes, ASCII)
body_len (u16 BE)
body     (body_len bytes)

Fields

kind: String

Plugin-namespaced kind identifier.

body: Bytes

Opaque payload bytes — interpretation is up to the plugin claiming kind.

Trait Implementations

impl Clone for ControlFrame

fn clone(&self) -> ControlFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ControlFrame

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

Formats the value using the given formatter.

impl FrameCodec for ControlFrame

fn encode(&self, buf: &mut BytesMut)

Encode self into the provided mutable buffer.

fn decode(buf: &mut BytesMut) -> Result<Self, PimError>

Decode one frame from the provided buffer.

impl PartialEq for ControlFrame

fn eq(&self, other: &ControlFrame) -> 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 Eq for ControlFrame
