A small and fast async runtime.
This crate simply re-exports other smaller async crates (see the source).
To use tokio-based libraries with smol, apply the [async-compat] adapter to futures and I/O
types.
Connect to an HTTP website, make a GET request, and pipe the response to the standard output:
```rust,no_run use smol::{io, net, prelude::*, Unblock};
fn main() -> io::Result<()> { smol::blockon(async { let mut stream = net::TcpStream::connect("example.com:80").await?; let req = b"GET / HTTP/1.1\r\nHost: example.com\r\nConnection: close\r\n\r\n"; stream.writeall(req).await?;
let mut stdout = Unblock::new(std::io::stdout());
io::copy(&stream, &mut stdout).await?;
Ok(())
})
} ```
There's a lot more in the [examples] directory.
Some code examples are using TLS for authentication. The repository contains a self-signed certificate usable for testing, but it should not be used for real-world scenarios. Browsers and tools like curl will show this certificate as insecure.
In browsers, accept the security prompt or use curl -k on the
command line to bypass security warnings.
The certificate file was generated using minica and openssl:
text
minica --domains localhost -ip-addresses 127.0.0.1 -ca-cert certificate.pem
openssl pkcs12 -export -out identity.pfx -inkey localhost/key.pem -in localhost/cert.pem
Another useful tool for making certificates is [mkcert].
