Advanced Hands-on Rust B2.0: Dependency name & version mix up - P57
Original message: At the bottom of P57, you search for the pcg random number crate. The search returns pcg_rand = "0.13.0", but in the Cargo.toml, you put rand_pcg = { version = "0,3", ...}
Cut & paste typo from the xorshift line?
EDIT:
Actually, I now realise the typo is the other way round! The rand_pcg crate is correct, so the result for cargo search pcg on P57 has the wrong output, and everything else is correct.
Apologies for the confusion - this only became apparent when trying to use Pcg64Mcg - it doesn’t exist in pcg-rand.
