Catching up with async Rust

In December 2023, a minor miracle happened: async fn in traits shipped.
As of Rust 1.39, we already had free-standing async functions:
pub async fn read_hosts() -> eyre::Result<Vec<u8>> {
// etc.
}
...and async functions in impl blocks:
impl HostReader {
pub async fn read_hosts(&self) -> eyre::Result<Vec<u8>
Frustrated? It's not you, it's Rust

Learning Rust is... an experience. An emotional journey. I've rarely been more frustrated than in my first few months of trying to learn Rust.
What makes it worse is that it doesn't matter how much prior experience you have, in Java, C#, C or C++ or otherwise - it'll still be unnerving.
In fact, more experience probably makes it worse! The habits have settled in deeper, and there's a certain expectation that, by now, you should be able to get that done in a shorter amount of time.

As I've said before, I'm working on a book about lifetimes. Or maybe it's just a long series - I haven't decided the specifics yet. Like every one of my series/book things, it's long, and it starts you off way in the periphery of the subject, and takes a lot of detours to get there.
In other words - it's great if you want an adventure (which truly understanding Rust definitely is), but it's not the best if you are currently on the puzzled end of a conversation with your neighborhood lifetime enforcer, the Rust compiler.
