We are launching a Variadic Generics Micro Survey.

This survey is meant to gather sentiment and use-cases for upcoming design discussions for adding variadic generics to the Rust language. Its main goal is to answer questions like "What do people think about variadic generics in Rust? How would people use them?". The answers will likely be used to provide more context for an upcoming RFC for variadic generics.

The survey is only offered in the English language.

We invite you to take this survey even if you have limited Rust experience, or you're not familiar at all with the concept of variadic generics. Every data point helps up paint a clearer picture.

You can fill out the survey here.

Filling the survey should take you approximately 5 minutes, and the survey is fully anonymous. We will accept submissions until Monday, October 20th, 2025.

Please help us spread the word by sharing the survey link via your social networks, at meetups, with colleagues, and in any other community that makes sense to you.

Thank you!
