“The Rust RFC Book” is an invaluable resource for any Rust programmer who wants to stay up to date with the latest changes in the programming language. It provides an overview of all the accepted RFCs (Request for Comments) in the Rust language, which are proposed and accepted by the Rust community. This guide will provide a comprehensive introduction to the Rust RFC book and how it can be used to your advantage.

To start, let’s take a look at what an RFC is and how they work in the Rust programming language. An RFC, or Request for Comments, is a document that outlines proposed changes or enhancements to a programming language, library, or tool. It will usually include details on how the change would be implemented as well as any potential risks that may arise from making the change. Once an RFC is proposed, it is discussed among members of the Rust community before being accepted into the language or rejected.

Once an RFC has been accepted into the Rust language, it will be added to the official Rust RFC book. This book serves as a record of all accepted RFCs and provides an overview of all changes made to the language over time. The book also includes details on each accepted proposal such as its purpose, technical details, and other relevant information.

Using this book can help you keep up with all developments made in the Rust programming language. It can provide a valuable resource when you need to understand how a specific feature works or want to find out if a particular change has been implemented in recent versions of Rust. By reviewing this book regularly, you can also ensure that your codebase remains up-to-date with all new changes made in Rust so you can take advantage of all its features and benefits.

In conclusion, the official Rust RFC book is an incredibly useful resource for any Rust programmer who wants to stay on top of all recent developments made in the programming language. It provides an overview of all accepted RFCs and gives you detailed

What is the RFC Process?

The Rust Request for Comments (RFC) process is a structured and collaborative way for the community to suggest and discuss changes to the Rust language. The RFC process is open to anyone who has an idea for a change to Rust, and encourages everyone in the community to participate in the discussion.

To start the RFC process, anyone can submit an RFC document that outlines their proposed change or feature. The document should be well-written and include a detailed description of the proposed change. Once submitted, other members of the community can provide feedback on the proposal.

The feedback can be technical in nature, discussing how a particular feature might affect the language or its performance, or it can focus on other aspects such as design or usability. This feedback helps refine the proposal and ensure that it meets the needs of all stakeholders.

Once a proposal has been discussed and refined, it will then enter into a Final Comment Period (FCP) where members of the community can cast their votes on whether or not to accept or reject the proposal. If accepted, the proposal will become part of the official Rust codebase.

The RFC process is an important part of keeping Rust open source and providing a place for everyone in the community to share their ideas and help shape its future. It also helps ensure that any changes to Rust are done with thoughtful consideration and input from all stakeholders, resulting in better features for everyone.


The Rust RFC process is a powerful tool for ensuring that changes to the language are well-thought out and thoughtfully considered. It’s a great way for the community to come together and share ideas and make sure that the language evolves in a way that is beneficial for everyone.

The RFC process is an important part of the Rust development process, and should be followed consistently. By following the process, everyone can have their voices heard and help shape the future of Rust.

It’s important to remember that RFCs are not a guarantee of implementation, but rather an opportunity for discussion and feedback. The Rust team will take all feedback into consideration when deciding whether or not to add a feature or change something in the language.

The RFC process also helps to ensure that changes to Rust are implemented in a consistent manner, which makes it easier for developers to understand how changes will affect their codebase.

Ultimately, it’s up to the Rust team to decide which RFCs should be implemented and which should be rejected. The Rust team will always take into account the opinions of the community when making such decisions.
