It's not really up to the curl people to rewrite it in rust.

It's for the proponents of rust.

Personally, I'm largely convinced that writing in rust will lead to safer implementations... now I'm just waiting for the full-featured, well-though-out, stable, useful rust implementations to appear.

I'm not married to curl. Where's "rurl" or whatever? If it exists and does something useful as well as curl (or better), I'll happily use it.

Well, curl is a bit of swiss army chainsaw for protocols and in general there is rarely a need to have same subsystem (of "downloading/sending something to an url) have support for protocols from HTTP thru IMAP all the way to LDAP.

So there is really no reason to use it Rust, use smaller, protocol-specific libs, less security problems and if you need multi-protocol support just switch by protocol and maybe write some wrappers.

And for calling it from C, "Rewrite it in Rust but make ABI C compatible" means you have to repeat a lot of Curl's idiosynchracies all while recreating all of the functionality. Looking at https://curl.se/docs/security.html there isn't that many of them that Rust safety would prevent so the real gains from that aren't probably all that great.

Now OpenSSL on another hand...

I'll just leave this here:

That would be a major effort, without a very clear benefit. Curl is massive, just scroll through its man page.

I just scrolled through the man page at a speed of 15 pages per second. Aside from that, curl is an extremely important and impressive piece of software that I use daily.

Massive and written in C, you'd be mad to use it ... oh

    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

The approaches C and Rust projects have to upgrades are so radically different, it's comical:

curl: let's not rush, 23 years is not enough time for people to update their compilers.

Rust: the compiler released last Thursday is the oldest supported version.

And start a rewrite themselves afterwards.
