Rustacean Station

A lively tour of the Rust 2024 Edition's biggest language and tooling changes. They hit RPIT lifetime capture rules, let-chain and temporary drop behavior, and match ergonomics restrictions. Unsafe-related shifts get lots of attention, from extern blocks to newly unsafe std functions. Cargo and rustdoc updates, macro fragment changes, and a reserved gen keyword round out the conversation.
