It depends on the TTS software involved: some were outright skipping the characters which is worse than the ASCII version, but I consider that to be a bug of that software.

It's a request for the following to be valid enum X { A, B, } fn foo() -> X::A { X::A } which helps a lot when composing state machines. In the meantime, you can indeed do what you propos

Both are valid Rust. The former means "I don't own var, but I can change it", while the later means "I own a reference that I can change where it points, but I can't change the pointed value." An argument could

And anyone that has learned (or just plain gotten used to) Rust in the last 3 years would be in for a shock if they tried to use Rust 1.0. Things have gotten better since. And I'd bet that it will continue to do so, at least for a wh

This new picture is in conversation with the older one, acknowledging its legacy while also making a statement. Is there anything about the new picture that is souless, beige, featureless or boring?

It's been a while since I started learning Rust, and have the advantage of learning new constructs as they are being implemented before they even hit stable, so I find it hard to put myself in your shoes. Could you give some examples o

There's a wide gulf between "one-off afternoon-long project done for fun" and "serving all traffic for amazon.com during black friday", so I am receptive to the "I can just do this one off thing in Perl".

Having examples of these is useful to see what we could get rustc to do. The general case might be impossible to deal with in a generic way, but we can target specific patterns libraries use and emit custom errors for them. The problem wi

I find it surprising that so many people are arguing about the benefits and drawbacks of `?`, when in my experience the handling of Result and Option haven't been an issue in practice on the consuming side (`?`, `.unwrap()`, `.map()`,

This is not an uncommon pitfall when working with strings in all languages. In Java for example it is drilled into people to use StringBuilder instead of concatenating with + on String if you do it in a loop, precisely because of this exact

Keep in mind that the people working on rustc are not the same working on rust-analyzer, even if there's some overlap in contributors and there's a desire to share libraries as much as possible. Someone working on speeding up rust

I can give you a straightforward example: the parser can recover from missing semicolons at the end of statements. The language could do automatic semicolon insertion a-la javascript. But then that means that all the ambiguous cases have
