Announcing async fn and return-position impl Trait in traits
(blog.rust-lang.org)
Aaaw yiiiss, been waiting for this, -> impl xxx
simplifies function signatures soo much, so not being allowed to do that in traits was a real pain
trait HttpService {
async fn fetch(&self, url: Url) -> HtmlBody;
// ^^^^^^^^ desugars to:
// fn fetch(&self, url: Url) -> impl Future;
}
Man I've been waiting for this to be stabilized for a long time. So excited about it.
