#![deny(warnings)] // This is using the `tokio` runtime. You'll need the following dependency: // // `tokio = { version = "1", features = ["full"] }` #[cfg(not(target_arch = "wasm32"))] #[tokio::main] async fn main() -> Result<(), reqwest::Error> { // Some simple CLI args requirements... let url = if let Some(url) = std::env::args().nth(1) { url } else { println!("No CLI URL provided, using default."); "https://hyper.rs".into() }; eprintln!("Fetching {url:?}..."); // reqwest::get() is a convenience function. // // In most cases, you should create/build a reqwest::Client and reuse // it for all requests. let res = reqwest::get(url).await?; eprintln!("Response: {:?} {}", res.version(), res.status()); eprintln!("Headers: {:#?}\n", res.headers()); let body = res.text().await?; println!("{body}"); Ok(()) } // The [cfg(not(target_arch = "wasm32"))] above prevent building the tokio::main function // for wasm32 target, because tokio isn't compatible with wasm32. // If you aren't building for wasm32, you don't need that line. // The two lines below avoid the "'main' function not found" error when building for wasm32 target. #[cfg(target_arch = "wasm32")] fn main() {}
