Sure, in areas without robust transit, transit is a problem. But I'm responding to RandallBrown's assertion that there's a persistent last mile issue in areas with robust transit. There's not. Manhattan is evidence that

I don't think that having two numbers will help much. I'd guess that most sim-swapped cell numbers are leaked in data breaches or acquired through data brokering. Enrolling a number in 2fa is letting people know your number, bec

It's an area of active development! I'm hopeful the situation will improve significantly this year. For tracing suspended Futures, I've worked on a few approaches: 1. If you don't mind annotating your async functions, yo

It only works if DWARF is generated. By default, the `release` profile of Cargo sets `debug = false` [0]. But, it's quite easy to override this setting, and have a build that is both optimized and includes debuginfo. [0]: https:/

Absolutely! That's the approach that frunk [0] takes. Frunk (and other reflection libraries like it) are suitable for most use cases, and make better use of Rust's affordances. My crate is suitable for cases where you cannot know

Yes, unfortunately that's a tradeoff here. Rust does support splitting debug info into other files, but Deflect doesn't support loading split debuginfo yet .

Oh, I should add a note about that. Fortunately, it's quite easy to tell Rust to generate debuginfo even in release mode.

> Also note that you have to go out of your way to get broken by such additions: you have to declare a trait, then implement that trait for a group of types that you didn't define, and then use that trait on standard library types.
