Stringing things along

Notes

This episode, I take a deep dive on strings in Rust, looking at the differences between String and &str, discussing Unicode a bit, and then expanding the discussion to think about how these types relate to the types they're built on (like Vec).

Corrigenda

Listener Nev pointed out to me that I got it wrong when describing how &str data is stored. It is not stack-allocated, but rather goes in the data segment. I should have said statically-allocated, not stack-allocated. Thanks to Nev for the correction!
