iftop does for network usage what top(1) does for CPU usage.

Written in Rust
RustNet leverages Rust's memory safety guarantees and performance characteristics, reducing common vulnerabilities like buffer overflows while maintaining speed comparable to C/C++.
Terminal UI for network monitoring
Provides a real-time, terminal-based interface for monitoring network connections, making it lightweight and usable over SSH or in headless environments without needing a GUI.
Low resource overhead
Being written in Rust and designed as a CLI/TUI tool, it likely has a smaller memory and CPU footprint compared to heavier network monitoring solutions with graphical interfaces.
Open source
The project is open source on GitHub, allowing users to inspect the code, contribute improvements, fork it for custom needs, and verify its behavior for security purposes.
Modern tooling and dependency ecosystem
By using Rust's Cargo ecosystem, RustNet can leverage well-maintained crates for networking, parsing, and terminal rendering, potentially speeding up development and improving reliability.

Relatively new/niche project
As a smaller or newer project compared to established tools like Wireshark, tcpdump, or nethogs, it may have a smaller community, less battle-testing, and fewer contributors reviewing the code.
Limited documentation
Newer open-source projects often have less comprehensive documentation, which can make it harder for users to understand advanced features, configuration options, or troubleshooting steps.
Potentially limited feature set
Compared to mature network analysis tools, RustNet may lack advanced features such as deep packet inspection, protocol dissection, or extensive filtering capabilities.
Platform support uncertainty
Depending on its implementation, it may have limited or untested support across different operating systems (Linux, macOS, Windows), which could restrict its usability in diverse environments.
Smaller community and support
With fewer users and contributors than established alternatives, finding help, plugins, or third-party integrations may be more difficult, and bug fixes may take longer to be addressed.

Real-time Monitoring
iftop provides real-time bandwidth monitoring, enabling users to quickly identify network usage and any potential issues.
User-Friendly Interface
The tool features a simple, text-based user interface that is easy to navigate, making it accessible for users with varying levels of experience.
Detailed Traffic Insight
iftop offers detailed information about network traffic, including source and destination IP addresses, service ports, and data flow rates.
Lightweight
Being a command-line tool, iftop is lightweight in nature and does not consume significant system resources.
Open Source
iftop is open source, allowing users to access, modify, and distribute the software freely, which can lead to community-driven improvements.

Lacks Historical Data
iftop does not have the capability to store historical data, making it unsuitable for long-term network monitoring and analysis.
Limited Features
Compared to other network monitoring tools, iftop has a limited feature set and may not meet the requirements of advanced network analysis needs.
Requires Root Permissions
The tool requires root or elevated permissions to run, which might be a security concern in certain environments.
Text-based Output
As a text-based tool, iftop may not provide the most visually appealing outputs, which can be a drawback for users who prefer graphical interfaces.
Not Cross-Platform
iftop is primarily designed for Unix-like systems and may not be available or easily operable on non-Unix platforms like Windows.
