The simple programs are sometimes the trickiest. Take wc for example, which prints the number of words, lines, characters, and bytes of its input. It’s surprisingly hard to write a correct version of that program. Let me show you why and how Rusts prevents most of the bugs by design. This interactive coding session is targeted towards beginners and intermediate Rust programmers.

Everything has a memory footprint. And for most types it is known at compile time. But how large is a slice ([T]) or a trait object (dyn Trait)? In this talk we’ll explore those types that only have a known size at runtime, bringing some clairty into terms like “dynamically sized”, “unsized” or “existential” types.
