title: A synchronous http client for rust?
body: <p>I'm looking for a low overhead HTTP client in Rust to create a custom runtime for AWS lambda. All the implementations that I find (including the official runtime from AWS) are based on hyper/tokio and I don't want the overhead nor the added binary weight.</p>
  
  <p>Do you know one ? Is there a reason <strong><em>all</em></strong> frameworks are based on tokio ?</p>
  
  <p>Thanks,</p>
