online

📶 Library to check your Internet connectivity

Features

• Both asynchronous and blocking implementations.
• IPv4 and IPv6 support.

How it works

• Tries to connect to Chrome captive portal (using its domain name).
• If fails, tries the Firefox one.
• If both fail, the second error is returned to help with diagnostics.

Install

The library is available on crates.io. In example, through cargo-edit:

cargo add online

Async

online = { version = "4.0.0",  default-features = false, features = ["tokio"] }

Use

📝 Please visit the examples and documentation to check the details.

use online::check;

println!("Online? {}", check(None).is_ok());
println!("Online (timeout)? {}", check(Some(5)).is_ok());

Examples

cargo run --example sync
cargo run --features="tokio-runtime" --example tokio
