**Zond Engine** is the core library powering the [Zond](https://github.com/zond-rs/zond) network mapping and discovery tool. It provides a lightweight, fast, and highly concurrent networking backend for packet crafting, protocol fingerprinting, and host discovery on Linux and macOS.

## Features

* **Network Discovery:** Fast, asynchronous host scanning using raw sockets or TCP connect fallbacks.
* **Protocol Fingerprinting:** Identify services, databases, and network devices using an embedded signature database.
* **System Profiling:** Gather detailed local network interface and system information.
* **Pluggable Architecture:** Easy to extend with custom packet parsers or discovery modules.

## Getting Started

To use the `zond-engine` in your own Rust project, add it as a dependency in your `Cargo.toml`:

```toml
[dependencies]
zond-engine = "0.4.0"
```

## Modules

This crate contains the following core modules:

* `core`: Shared data structures, constants, and utilities.
* `protocols`: Network protocol parsers and packet crafting (TCP, UDP, ICMP, DNS, MDNS, etc.).
* `plugins`: Extendable modules for specific application-layer interactions or advanced enumeration.
* `system`: OS-level utilities (interfaces, firewall status, local processes) for Linux and macOS.
* `scanner`: The main asynchronous scanner, host resolution, and core orchestration logic.

## Compatibility

* **Supported Platforms:** Linux, macOS
* **Unsupported:** Windows is not currently supported.
