speedtest-rs

a tool like speedtest-cli, but in Rust

Status: This is usable for lower-end residential connections using "HTTP Legacy Fallback"

HTTP Legacy Fallback

This tool currently only supports HTTP Legacy Fallback for testing.

High bandwidth connections higher than ~200Mbps may return incorrect results!

The testing operations are different from socket versions of tools connecting to speedtest.net infrastructure. In the many FOSS Go versions, tests are done to find an amount of data that can run for a default of 3 seconds over some TCP connection. In particular, speedtest-cli and speedtest-rs tests with what Ookla calls the "HTTP Legacy Fallback" for hosts that cannot establish a direct TCP connection.

Ookla speedtest now has their own non-FOSS CLI tool that's native and available for many platforms.

TCP-based
Higher Bandwidth capable.

Please look here. Unfortunately, it is not FOSS. Still, it is supported by them and can be used for non-commercial purposes.

Purpose

This is a learning exercise for me to learn Rust and keeping up with its ecosystem.

The HTTP Legacy Fallback is currently based on the popular Python implementation:

https://github.com/sivel/speedtest-cli @ 2.1.2

There are also other speedtest.net using tools using different approaches to be stolen from in the future. For example:

https://github.com/traetox/speedtest

This example seems different as it appears to just use TCP connections and some protocol. It's probably more suitable to high-speed connections. TODO: Add a default TCP-mode.
