Struct GeneveHeader 

pub struct GeneveHeader {
    pub control: bool,
    pub protocol: u16,
    pub vni: u32,
}

A parsed Tailscale Geneve fixed header.

Fields

control: bool

The “Control” (C) bit: set when the payload is a control message (the relay bind handshake) rather than tunneled data.

protocol: u16

The inner protocol type (GENEVE_PROTOCOL_DISCO / GENEVE_PROTOCOL_WIREGUARD).

vni: u32

The 24-bit Virtual Network Identifier.

Implementations

impl GeneveHeader

pub fn parse(buf: &[u8]) -> Result<(GeneveHeader, usize), GeneveError>

Parse a Geneve fixed header from the front of buf. Returns the header and the offset of the inner payload (always GENEVE_FIXED_HEADER_LEN). Rejects a non-zero version or option length (Tailscale emits neither) so a malformed/foreign Geneve packet is not mis-decoded.

pub fn encode(&self) -> [u8; 8]

Encode this header into an 8-byte fixed Geneve header (no variable options).

Trait Implementations

impl Clone for GeneveHeader

fn clone(&self) -> GeneveHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GeneveHeader

impl Debug for GeneveHeader

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

Formats the value using the given formatter.

impl Eq for GeneveHeader

impl PartialEq for GeneveHeader

fn eq(&self, other: &GeneveHeader) -> 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.
