Crate netspeed_cli 

netspeed-cli

A command-line internet bandwidth tester using speedtest.net servers.

Overview

This crate provides both a library and a binary (netspeed-cli) for measuring download speed, upload speed, latency, jitter, and latency under load. It connects to speedtest.net’s server infrastructure to perform real-world bandwidth tests.

Modules

• cli — Command-line argument parsing with clap
• common — Shared utilities (bandwidth calculation, formatting, validation)
• config — Configuration merging (CLI args + config file)
• download — Multi-stream download bandwidth measurement
• upload — Multi-stream upload bandwidth measurement
• error — Unified error types
• formatter — Output formatting (detailed, simple, JSON, CSV)
• history — Persistent test result history
• http — HTTP client creation and IP discovery
• progress — Terminal progress bars and spinners
• servers — Server discovery, distance calculation, and selection
• test_runner — Test orchestration with template method pattern
• types — Shared data structures (Server, TestResult, etc.)
