### How the goal process works

**Project goals** are proposed bottom-up by a **point of contact**, somebody who is willing to commit resources (time, money, leadership) to seeing the work get done. The owner identifies the problem they want to address and sketches the solution of how they want to do so. They also identify the support they will need from the Rust teams (typically things like review bandwidth or feedback on RFCs). Teams then read the goals and provide feedback. If the goal is approved, teams are committing to support the owner in their work.

If the goal is approved, teams are committing to support the point of contact in their work.

Project goals can vary in scope from an internal refactoring that affects only one team to a larger cross-cutting initiative. No matter its scope, accepting a goal should never be interpreted as a promise that the team will make any future decision (e.g., accepting an RFC that has yet to be written). Rather, it is a promise that the team are aligned on the contents of the goal thus far (including the design axioms and other notes) and will prioritize giving feedback and support as needed.

* **Rust must deliver on its promise of peak performance and high reliability.** Rust’s maximum advantage is in applications that require peak performance or low-level systems capabilities. We must continue to innovate and support those areas above all.
* **Rust's goals require high productivity and ergonomics.** Being attentive to ergonomics broadens Rust impact by making it more appealing for projects that value reliability and maintenance but which don't have strict performance requirements.
* **Slow and steady wins the race.** For this first round of goals, we want a small set that can be completed without undue stress. As the Rust open source org continues to grow, the set of goals can grow in size.
* **Slow and steady wins the race.** We don't want to create stress via unrealistic, ambitious goals. We want to make steady progress each goal period on important problems.

#### Why these particular flagship goals?

[**Async.**](./async.md) Rust is a great fit for server development thanks to its ability to scale to very high load while retaining low memory usage and tight tail latency. 52% of the respondents in the [2023 Rust survey](https://blog.rust-lang.org/2024/02/19/2023-Rust-Annual-Survey-2023-results.html) indicated that they use Rust to build server-side or backend applications. In [2025H1 our plan](./async.md) is to deliver (a) improved support for async-fn-in-traits, completely subsuming the functionality of the [`async-trait` crate](https://crates.io/crates/async-trait); (b) finalize a design for sync and async generators, simplifying the creation of iterators and async data streams; (c) and improve the ergonomics of `Pin`, making lower-level async coding more approachable. These items together start to unblock the creation of the next generation of async libraries in the wider ecosystem, as progress there has been blocked on a stable solution for async traits and streams.

[**Rust for Linux.**](./rfl.md) The [experimental support for Rust development in the Linux kernel][RFL.com] is a watershed moment for Rust, demonstrating to the world that Rust is indeed a true alternative to C. Currently the Linux kernel support depends on a wide variety of unstable features in Rust; these same features block other embedded and low-level systems applications. We are working to stabilize all of these features so that RFL can be built on a stable toolchain. As we have successfully stabilized the majority of the language features used by RFL, we plan in 2025H1 to turn our focus to compiler flags and tooling options. We will (a) implement [RFC #3716] which lays out a design for ABI-modifying flags; (b) take the first step towards stabilizing [`build-std`](https://doc.rust-lang.org/cargo/reference/unstable.html#build-std) by [creating a stable way to rebuild core with specific compiler options](./build-std.md); (c) extending rustdoc, clippy, and the compiler with features that extract metadata for integration into other build systems (in this case, the kernel's build system).
