I am the sole maintainer of time, which is a foundational crate in the Rust ecosystem, having over 250 million all-time downloads. In maintaining time, I have pushed the boundaries of what is possible with the compiler, improved performance by adapting well-known algorithms, and implemented best-in-class formatting and parsing support. I also maintain the num_threads, deranged, powerfmt, and num-conv crates.

On top of time, I contribute to the Rust compiler and standard library, which led to me being part of the first-ever group of Rust Foundation fellows. I've been working with Rust in some form since 2016, and working on Rust itself since 2020. In this time, I have written two accepted RFCs (one stabilized, one being implemented), worked on eliminating special-casing for the standard library, and stabilized countless library items.

If you have used #[derive(Default)] on enums, mut(in path) on a field, or impl(in path) on a trait, that is a direct result of my RFC work. A more thorough list of my non-trivial contributions is available on my website.

I work on open source software in my free time. Sponsoring me shows that you believe the work I am doing is worthwhile and I should continue doing so. With your support, Rust and its ecosystem will be better off. The more support I have, the more time I am able to dedicate to work on Rust and its ecosystem.

@jhpratt

A sizeable number of people believe in my work and think that it should continue. With your support, Rust will become a better language and have a better ecosystem.
