Module network 

Network functionality for Scarlet

This module provides network capabilities including sockets and protocol stacks. It follows the existing patterns established by VfsManager and DeviceManager.

Architecture

• SocketObject: KernelObject type representing network endpoints
• NetworkManager: Global manager handling socket lifecycle and connections
• Socket Implementations: Provided by ABI modules (Linux, xv6, etc.)

Design Philosophy

Scarlet’s core provides only abstract socket infrastructure. Specific socket implementations (Unix domain sockets, TCP/IP, etc.) are delegated to ABI modules. This maintains Scarlet’s OS-agnostic nature while allowing each ABI to provide the socket semantics expected by its applications.

Usage

ABI modules implement SocketObject trait and register socket implementations with the NetworkManager.
