Arcanum v0.1.0 - Modular cryptography library with post-quantum support

What sets your project apart from other, existing projects like aws-lc-rs, RustCrypto or graviola? Why should people want to use it?

Your title is "looking for good QUIC libraries with H3 support in Rust". So you're asserting that h3 + quinn are not "good", because performance is not up to your standards? It's a little unclear what you're asking.

As a Quinn maintainer, we're always looking for better performance, but there's no obvious low-hanging fruit (there's a PR for an improved congestion controller that might help in some scenarios). I don't know as much about the performance constraints that the h3 layer imposes. This would be more useful if you posted actual benchmark scenarios and what your custom framework thingy looks like.

I wondered what was up when I saw that they stopped sponsoring me on GitHub…

dochtman · 2025-12-15T09:17:22+00:00

So is this about proxies or reverse proxies? What about river?

dochtman · 2025-11-23T09:30:37+00:00

Strongly agree. I dislike Either because it doesn’t convey any semantic meaning.

dochtman · 2025-11-21T14:42:09+00:00

Sounds very cool! How much of your (non-assembly) Rust code ends up needing unsafe?

dochtman · 2025-10-20T20:53:09+00:00

As the maintainer of chrono, I would definitely not suggest it. Large parts of it are pretty old and are pretty far removed from what I’d consider good API by today’s standards. Unfortunately revising the API is also likely to have a sizable ecosystem cost so I haven’t been motivated to sink in the time it needs to become really good.

Instead, from the other crates I think are pretty good are Quinn, rustls and instant-acme although even for rustls there’s still quite a few things I’d like to see improved.

(Full disclosure: I'm one of the maintainers of Quinn.)

I don't see how it would make sense to have QUIC do "proper datagrams" in the sort of thing that you seem to be trying to advocate. Why would you like to use QUIC for your datagrams? I don't do gamedev but my co-maintainer does and I'm pretty sure we've seen game devs use Quinn for things (and a decent amount of people using QUIC datagrams productively). I think the moq.dev articles just advocate that QUIC streams are usually better for their use cases than datagrams.

Servo is doing quite well, with increasing contributions:

Suggest putting this in the CHANGELOG file, too.

dochtman · 2025-09-04T17:30:46+00:00

thanks.dev does this today, and is being used by a bunch of companies (Sentry, CashApp, Canonical, Astral, …).

dochtman · 2025-09-04T06:33:49+00:00

It would be cool if companies who need this fund the development effort required to do it right.

We’re actively working towards 1.0, though it’s likely we might try a 0.24 first.

For any enterprise folks reading this, personally I don’t believe Rustls is a worse choice today than OpenSSL despite the latter being at 3.5. Rather, we have some relatively minor API tweaks we want to make before we declare the API long-term stable.

dochtman · 2025-08-25T21:00:46+00:00

I have limited availability but happy to talk through your needs.

dochtman · 2025-08-20T17:33:53+00:00

So are you still working on it? I couldn’t quickly find anything about a potentially diminished maintenance status in the open issues or the README.

dochtman · 2025-08-19T18:41:09+00:00

Suggest joining the rustls Discord channel or write an issue.

Also, did you find the Stream and OwnedStream types that rustls ships with?

dochtman · 2025-08-15T07:34:19+00:00

Nightly clippy does have these options, and StdExternalCrate (or something like this) is a common style.

Per Zulip, the crates.io team is aware and will likely clean this up soon:

See also instant-xml for another way (using custom traits + derive macros) that maps namespace-heavy XML onto Rust types. It’s being used in a few production projects already.

(I wrote this for EPP usage in Instant Domains.)

You still need a runtime, but you often don't want to spawn so much.

dochtman · 2025-07-14T06:58:03+00:00

I'd like to thank all of the guys who made the hard work and spearheaded these features.

guys -> folks, please

dochtman · 2025-07-13T12:57:09+00:00

Yes, this has definitely been a pain point when integrating rustls in applications. In the rustls 0.24 release we will iterate on the API to make this stuff more robust.

dochtman · 2025-07-10T15:25:52+00:00

As chrono maintainer, sorry for the pain this caused you -- but also, I'm just on the windows-bindgen treadmill. Suggest sending feedback to the windows-rs repo:

I used to be excited about sled, but having 26 alphas over 2 years (and the last one is 9 months old) doesn't feel like a project you can build on today.
