How to Write an RFC for Rust

Write an RFC by proposing a feature in the rust-lang/rfcs repo, discussing it, and creating a tracking issue in the main rust repo for implementation and stabilization.

You write an RFC by proposing a feature in the rust-lang/rfcs repository, discussing it on the internals forum, and then creating a tracking issue in the main rust repository once accepted. The process involves drafting the RFC, gathering community feedback, implementing the feature behind a feature gate like #![feature(my_feature)], and finally stabilizing it through a stabilization PR.

# Title: My New Feature

## Summary

A short description of the feature.

## Motivation

Why this feature is needed.

## Detailed Design

The technical implementation details.

## Unresolved Questions

Any open questions that need answering before stabilization.

Once the RFC is accepted, you create a tracking issue in the rust repository using the Tracking Issue template, which includes steps for implementation, documentation, and stabilization.

An RFC (Request for Comments) is a formal proposal to add a new feature or change the Rust language. It matters because it ensures all changes are discussed openly and carefully before being added, preventing breaking changes. Think of it like submitting a blueprint for a new building to a city council for approval before construction begins.
