nex

Cross-platform networking library in Rust

Overview

nex is a Rust library that provides cross-platform low-level networking capabilities.
It includes a set of modules, each with a specific focus:

• datalink: Datalink layer networking.
• packet: Low-level packet parsing and building.
• packet-builder: High-level packet building.
• socket: Socket-related functionality.

Upcoming Features

The project has plans to enhance nex with the following features:

• More Protocol Support: Expanding protocol support to include additional network protocols and standards.
• Performance Improvements: Continuously working on performance enhancements for faster network operations.

Usage

To use nex, add it as a dependency in your Cargo.toml:

[dependencies]
nex = "0.10"

Using Specific Sub-crates

You can also directly use specific sub-crates by importing them individually.

• nex-datalink
• nex-packet
• nex-packet-builder
• nex-socket

If you want to focus on network interfaces, you can use the netdev.

for Windows Users

Please note that in order to send and receive raw packets using nex-datalink on Windows, npcap is required.

1. Install Npcap, making sure to check Install Npcap in WinPcap API-compatible Mode during the installation.

2. Download the Npcap SDK. Add the SDK's /Lib/x64 (or /Lib) folder to your LIB environment variable.

To simplify the process of downloading and installing npcap, you can use nex-npcap-helper. This crate facilitates the download and installation process, which can be helpful when distributing applications that utilize nex-datalink on Windows.

Build time requirements for optional feature

The cryptography provider for nex-socket's optional tls feature use aws-lc-rs. Note that this has some implications on build-time tool requirements, such as requiring cmake on all platforms and nasm on Windows.
