A cross-platform Rust library for low-level network packet manipulation and protocol implementation.
libpnet is a cross-platform Rust library that provides a safe, high-performance API for low-level networking tasks. It enables developers to work directly with network packets, implement custom transport-layer protocols, and access the data link layer, all while leveraging Rust's memory and thread safety guarantees to avoid common C-level vulnerabilities.
Rust developers and network engineers who need to perform packet manipulation, develop custom transport protocols, or create network diagnostic tools and utilities.
Developers choose libpnet because it combines the performance of C with the safety and high-level abstractions of Rust, offering a unique solution for low-level networking without sacrificing reliability or speed, unlike scripting languages or unsafe C code.
Cross-platform, low level networking using the Rust programming language.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages Rust's guarantees to prevent common vulnerabilities like buffer overflows and use-after-free, as highlighted in the comparison to C-based networking.
Provides zero-copy packet parsing and construction through the packet module, ensuring efficiency similar to C without safety compromises.
Works on multiple operating systems with appropriate backends, such as WinPcap on Windows, making it versatile for different environments.
Offers the transport module for implementing transport-layer protocols, enabling creation of alternatives to TCP with safe abstractions.
On Windows, building requires installing WinPcap or npcap and manually placing Packet.lib, adding steps not needed in higher-level networking libraries.
Many networking tests and operations require running as root or admin, as noted in the README, which can complicate development and deployment workflows.
Lacks higher-level abstractions for common networking tasks, making it overkill for simple applications and limiting its ecosystem compared to more general-purpose libraries.
