Crate nexcore_network 

nexcore-network — NexCore OS Networking Subsystem

Tier: T3 (Σ + μ + ∂ + ς + σ + π + ∝ + N + ν + κ + → + λ + ∃)

Complete networking stack for NexCore OS sitting above nexcore-pal::Network. Manages interfaces, connections, DNS, routing, firewall rules, traffic monitoring, and TLS certificate trust stores across all three form factors (watch, phone, desktop).

Module Architecture

Module	Tier	Dominant	Purpose
interface	T2-C	Σ + μ + ∃	Network interface abstraction
connection	T2-C	ς + σ + ∂	Connection state machine
dns	T2-C	μ + π + ν	DNS resolver with caching
firewall	T2-C	∂ + κ + →	Packet filtering rules
route	T2-C	→ + κ + λ	Routing table with prefix matching
monitor	T2-C	N + ν + σ	Bandwidth, latency, and quality tracking
certificate	T2-C	∂ + π + ∝	TLS certificate trust store

Example

use nexcore_network::{Interface, InterfaceType, IpAddr, Connection, ConnectionState};

// Create a WiFi interface
let iface = Interface::new("wlan0", "wlan0", InterfaceType::WiFi)
    .up()
    .with_address(IpAddr::v4(192, 168, 1, 100));

assert!(iface.is_up);
assert_eq!(iface.interface_type, InterfaceType::WiFi);

// Create a connection tracking its lifecycle
let conn = Connection::new(iface.id.clone(), iface.interface_type, "HomeWiFi");
assert_eq!(conn.state(), ConnectionState::Disconnected);

Modules

certificate

TLS certificate management — trust store for secure connections.

composites

Composite Types

connection

Connection state machine — the lifecycle of a network connection.

dns

DNS resolver with caching.

firewall

Firewall — packet filtering rules for OS-level network security.

interface

Network interface abstraction.

monitor

Traffic monitoring — bandwidth, latency, and connection quality tracking.

prelude

Prelude — nexcore-network

route

Routing table — determines which interface handles which traffic.
