tl;dr - hyper in curl is nearly complete, but it needs a champion. Without a partner actively engaged that wants to enable and ship, it’s now on the path for being deprecated and removed.

hyper is the most mature HTTP library written in Rust. By making hyper a possible HTTP backend for curl, the code used for the most ubiquituous protocol could be made safer. Certainly true for HTTP/1, even more so with the much bigger (code-wise) HTTP/2 and HTTP/3.

In 2020, we started exploring the idea. I designed and built a C API for hyper. Daniel refactored curl to allow for HTTP backends, and integrated hyper.

We got it nearly complete. Adventurous tinkerers were able to build and use it on their personal machines. Over 95% of curl’s large test suite was passing.

But the upkeep of the feature isn’t free, in both the curl and hyper repositories. Because of that, and without a commited organization wanting to ship it, it’s planned to be removed at the start of 2025.
