RustConf 2025 took place September 2–5, 2025, at the Hyatt Regency in Seattle and online. Hosted by the Rust Foundation, it brought together talks on Rust’s future, production use, async programming, AI, memory safety, and more. The event has ended; the Foundation’s retrospective links to keynote, session, and sponsor-talk recordings, plus a highlight reel and photo gallery.
What RustConf 2025 was
RustConf is an annual conference for people building, maintaining, and using the Rust programming language and its ecosystem. It is not a compiler-release event or solely an academic conference: its program spans engineering practice, project direction, production adoption, tooling, infrastructure, and community. The Rust Foundation organized and hosted the 2025 event. The official event listing describes the Foundation’s role in supporting Rust’s infrastructure, tooling, administration, and community investment.
Rust 1.0 reached its tenth anniversary in 2025, but the conference’s framing looked ahead to Rust’s next decade. The program explored how Rust is being applied beyond traditional systems programming, including cloud services, application development, AI, edge and embedded systems, and interoperability with C and C++. These were conference themes, not a claim that every area has reached the same level of adoption.

Dates, venue, and format
The four-day event combined workshops and registration, two main conference days, and a participant-driven UnConference. The in-person venue was the Hyatt Regency at 808 Howell Street, Seattle, Washington 98101. Online attendance was also offered.

| Date | What was scheduled |
|---|---|

The online ticket was advertised at $0 during registration, with livestreamed talks, interactive Q&A through Discord, and recordings afterward. That was a historical event offer, not an open registration option now. Workshops were separately registered, capacity-limited sessions for in-person attendees; a livestream or talk archive is not a substitute for their hands-on format. See the registration announcement and program announcement for the original format and schedule.
Talks and themes to explore
The published program covered a wide range rather than focusing on one technical specialty. These examples help readers find talks relevant to their interests; they are not a ranking, and the final schedule or recording metadata is the best reference for exact titles and delivery.
Rank #2
- Rust’s direction: Rust Project members Niko Matsakis and Jack Huey discussed the Vision Doc and the language’s next decade.
- Cloud and production adoption: Mark Russinovich of Microsoft Azure addressed Microsoft’s growing use of Rust and its implications for cloud security and reliability. Yuri Astrakhan discussed Rust adoption at Rivian, while Danilo Chiarlone and Ludvig Liljenberg covered Microsoft’s Hyperlight project.
- Building applications: Ellie Huxtable of Atuin spoke about using Rust across CLI, UI, and backend contexts; Jonathan Kelley of Dioxus addressed high-level Rust and application development.
- Async and interoperability: The program included async design and API topics, as well as Taylor Cramer and Tyler Mandry on fine-grained C++ interoperability.
- AI, accelerated computing, and edge: Nathaniel Simard of Tracel-AI covered Rust for AI and accelerated computing. The workshop program also included real-world inference and edge deployment.
- Memory safety and language interop: Chandler Carruth of Google and Carbon explored memory safety and the relationship between Rust and Carbon.
- Systems and robotics: Jeremy Soller discussed ten years of Redox OS and Rust; Yang Zhou presented on Rust for robotics.
- Maintainer infrastructure: Rust Foundation staff member Marco Ieni discussed reducing Rust CI costs, a practical topic for teams paying to build and test large projects.

The retrospective describes four hands-on workshop themes: async design patterns; async and C++ interoperability; fundamentals of async APIs in Rust; and “Rust at the Edge: AI Development, Edge Deployment, Real-World Inference.” Workshops were separately registered and capacity-limited. They were designed for in-person participation rather than as part of the free virtual-talk experience.
Rank #3
The September 5 UnConference was deliberately less formal than a conventional track of scheduled talks. It emphasized participant-led discussion, hallway conversations, whiteboarding, impromptu presentations, and collaborative problem-solving. It should not be mistaken for a standard recorded session track; not every discussion was necessarily recorded.
Two notable Foundation and ecosystem announcements
Rust Innovation Lab launched with rustls
On September 3, the Rust Foundation announced the Rust Innovation Lab, naming rustls as its inaugural project. The initiative is intended to give qualifying open-source projects institutional support such as fiscal sponsorship, governance, legal, networking, marketing, and administrative assistance. It is an ecosystem-support program, not a Rust language or compiler release, and its stated purpose should not be confused with proof of specific outcomes for project security or sustainability. Details are in the Foundation announcement.
Arm moved to Platinum Foundation membership
Arm upgraded its Rust Foundation membership from Silver to Platinum, the Foundation’s highest membership level. The Foundation connected the support to Rust’s relevance in areas including cloud, embedded systems, IoT, and security. The membership is a notable industry-support signal, but by itself does not establish industry-wide adoption or dominance. Read the Arm membership announcement.

Start with the Rust Foundation’s official retrospective. It links to full keynote, session, and sponsor-talk recordings, as well as a highlight reel and photo gallery. The following is an editorial way to choose what to watch, based on the announced subjects:
- For Rust’s future: Niko Matsakis and Jack Huey on the Vision Doc.
- For cloud and enterprise engineering: Mark Russinovich on Microsoft’s Rust use; the Rivian and Hyperlight sessions for additional production perspectives.
- For async developers: Look for the async sessions and workshop descriptions; a recording may not provide the exercises or interaction of a hands-on workshop.
- For AI and edge computing: Nathaniel Simard’s accelerated-computing session and the edge-AI material.
- For memory safety and interoperability: Chandler Carruth on Rust and Carbon, and Taylor Cramer and Tyler Mandry on C++ interoperability.
- For maintainers and infrastructure teams: Marco Ieni on CI costs, alongside the Rust Innovation Lab announcement.
- For operating systems and robotics: Jeremy Soller on Redox OS and Yang Zhou on robotics.
Some presentations are sponsor talks. They can still contain useful technical information, but readers should recognize their sponsor context rather than treating them as independent conference conclusions. Also, these recordings document the state of projects and arguments in 2025; verify current APIs, plans, and company positions against newer sources before relying on them for a 2026 implementation decision.
Who sponsored the event?
The Foundation’s final retrospective lists Solana Foundation as Diamond sponsor. Gold sponsors were Antithesis, Amazon Web Services, corust.ai, Google, JetBrains, Meta, Microsoft, Mimic, Oracle, Polar Signals, Virtu Financial, and Zed Industries. Arm was a Silver sponsor; ai-coustics and Ardan Labs sponsored workshops. The final list is useful context for the event, particularly when choosing sponsor presentations, but sponsorship alone does not validate a talk’s technical claims.
RustConf 2025 and RustConf 2026 are different events
RustConf 2025 was held in Seattle from September 2–5, 2025. The next event, RustConf 2026, is scheduled for September 8–11, 2026, in Montreal, Canada, with an online experience. Current RustConf pages may foreground 2026, so check the year before using a schedule or event link.
