Struct NodeID 

pub struct NodeID(/* private fields */);

Unique identifier for a peer in the P2P network.

NodeID is a 4-byte identifier typically based on an IPv4 address. Each peer in the network must have a unique NodeID for routing purposes.

Examples

use rustp2p::NodeID;
use std::net::Ipv4Addr;

// Create from IPv4 address
let node_id: NodeID = Ipv4Addr::new(10, 0, 0, 1).into();

// Create from u32
let node_id: NodeID = 0x0A000001u32.into();

// Convert back to IPv4
let addr: Ipv4Addr = node_id.into();
assert_eq!(addr, Ipv4Addr::new(10, 0, 0, 1));

Implementations

impl NodeID

pub fn broadcast() -> NodeID

Returns a broadcast NodeID (255.255.255.255).

Messages sent to this ID will be broadcast to all peers.

Examples

use rustp2p::NodeID;

let broadcast = NodeID::broadcast();
assert!(broadcast.is_broadcast());

pub fn unspecified() -> NodeID

Returns an unspecified NodeID (0.0.0.0).

Examples

use rustp2p::NodeID;

let unspec = NodeID::unspecified();
assert!(unspec.is_unspecified());

pub fn is_unspecified(&self) -> bool

Checks if this NodeID is unspecified (all zeros).

Examples

use rustp2p::NodeID;

let unspec = NodeID::unspecified();
assert!(unspec.is_unspecified());

pub fn is_broadcast(&self) -> bool

Checks if this NodeID is a broadcast address (all 255s).

Examples

use rustp2p::NodeID;

let broadcast = NodeID::broadcast();
assert!(broadcast.is_broadcast());
