Explore an introduction to structs, traits, and zero-cost abstractions in Rust through this 22-minute conference talk recorded at the Rust KW Meetup in Kitchener-Waterloo, Canada. Gain insights into building efficient abstractions and writing better code without compromising performance. Learn about structs, traits, generics, and their applications in Rust programming. Discover the concept of zero-cost abstractions and their benefits. Examine practical examples, including append-only vectors and logger implementations. Compare dynamic dispatch with trait objects to generics, and understand their impact on optimization. Ideal for programmers experienced in other languages but new to Rust.
