New week, new Rust! What are you folks up to?

I'm hoping to finalise a few proc-macros(try_v2, exit_safely) that I started on in true "pass the salt (xkcd)" style. Maybe I'll also break out the half-finished implementation of Diagnostic for proc-macro2 that I embedded into them too...

Then I'll take another look at trying to get an async backend and an event-loop front-end to play nicely together in a way that compiles to wasm (a personal project I put on the back burner 9 months ago). I only managed to get 2 out of 3 last time I looked at it ;(

I got around to updating Rust Learning to account for various Rust developments...

  • Builtin supertrait upcasting
  • Precise capturing and changes to default RPIT captures
  • _ being available to infer const parameters
  • TypeId::of being a const fn
  • Being able to omit where Self: Sized trait methods in unsized type impls
  • Being able to coerce away the dyn principal trait
  • mismatched_lifetime_syntaxes warn-by-default lint
  • elided_lifetimes_in_associated_constant future compatibility lint

Later this week I'll reread the guide with fresher eyes in an attempt to clean up the various typos and poor wordings I inevitably also introduced.
