history

Project history and usage

havn is a lightweight Rust port scanner with configurable defaults. The README describes it as a self-contained TCP scanning application using Tokio multithreading, with Docker and multi-platform binary distribution.

Project history

The project history is compact and well documented in its changelog. Version 0.1.0 on 2023-05-18 is listed as the initial commit. Subsequent 0.1.x releases refined documentation, CLI argument descriptions, spinner/color behavior, tests, and maintenance automation.

By 2025, the changelog shows feature work such as a Rust 2024 edition update and verbose mode. The 0.3.x line continued performance and release-workflow adjustments while retaining the small single-purpose scope of a fast configurable scanner.

Adoption history

havn is distributed through Cargo, prebuilt GitHub release archives, Docker Hub, GitHub Container Registry, Arch Linux repositories, x-cmd, and Homebrew package metadata. That gives a small Rust CLI several installation paths without turning it into a larger framework.

Its adoption is likely among users who want a quick TCP port scan with sane defaults, concurrent scanning, IPv4/IPv6 selection, configurable ranges, retries, timeouts, Docker support, and a small binary footprint.

How it is used

Typical use is direct CLI scanning: run havn with a host or address, optionally select all ports or a range, set concurrency, timeout, retry count, monochrome output, IPv6 mode, or verbose output.

The README examples cover scanning github.com with defaults, scanning localhost across all ports with custom concurrency and timeout, scanning specific host/port ranges, and scanning one port with retries.

Why package nerds care

havn is package-nerd relevant as a small Rust network utility that ships through several channels: cargo install for Rust users, prebuilt release archives for direct installs, containers for isolated runs, and OS package managers for system-managed installs.

Its changelog is intentionally granular, recording maintenance items such as dependency updates, Rust lint changes, release-script updates, and CI workflow changes. That is useful to package maintainers because build tooling and Rust edition changes can affect downstream packaging even when CLI behavior barely changes.
