Crate netrunner_core 

netrunner-core

Framework-free internet speed-test and network-diagnostics engine shared by the netrunner_cli (Ratatui TUI) and netrunner (Zed GPUI desktop) apps, and usable as a standalone library.

Module	What lives here
types	Domain models — results, servers, config, quality ratings, diagnostics
speed_test	Geolocation, server discovery/selection, throughput & latency measurement (SpeedTest)
diagnostics	Gateway/DNS/route/IPv6 network diagnostics (NetworkDiagnosticsTool)
history	Embedded redb history storage & statistics (HistoryStorage)
events	UI-agnostic progress events (TestEvent) streamed over a channel

This crate has no GUI or TUI dependencies. Progress is reported through TestEvents so any front-end can render it.

Quick start

use netrunner_core::{SpeedTest, TestConfig};

let test = SpeedTest::new(TestConfig::default())?;
let result = test.run_full_test().await?;
println!("{:.1} Mbps down / {:.1} Mbps up", result.download_mbps, result.upload_mbps);
