Fix header levels of 3641
Nice to knowtooling
- What changed
- The RFC template was updated after this RFC was created to not use level‑1 headers.
- Production impact
- The source does not say.
- Try it
- Open the RFC text to see the new header formatting.

- github.com/rust-lang/rfcs/pull/3932
Understand it, then run it
The RFC template was updated to stop using level‑1 headers. Previously an RFC started with a top‑level # header, which made the title look like a normal heading. The change removes that first #, so the title is now plain text, and the first header in the document is level‑2 (##). This keeps the title separate from the rest of the content and matches the style used in other RFCs.
Run it now
// This program simply demonstrates the updated RFC header style.
// It prints a message that the RFC title is now plain text,
// and the first Markdown header starts with `##`.
// No network or external input is required.
fn main() {
// The title of an RFC is plain text, not a level‑1 header.
println!("RFC title is plain text, not a level‑1 header.");
// The first header in the body should be level‑2 (`##`).
println!("First header in the body should start with `##`.");
}
What it printed when we ran it on Rust 1.98.1 (edition 2024)
RFC title is plain text, not a level‑1 header. First header in the body should start with `##`.
Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
