rust question. a common pattern in code i’ve written is:

assert!(foo % bar == 0);
let count = foo / bar;

is there a standard way to do that as a single operation?

one of the things i really like about rust is how it helps you avoid errors by combining an assertion of some assumption (e.g. “foo is not None”) with obtaining a value based on that assumption (e.g. getting the value inside the Some()). so in this case, it’d be really nice if i could do something like foo.div_exact(bar).unwrap(). personally i’d put it in the stdlib…

oh no, I just had to reboot my server after it became unresponsive. it seems like it might have been serving a lot of fediverse requests, was it overwhelmed?

I hope that was legit traffic and not an attack. I should look up what domains are suspicious…

it's incredibly cute how ARMv6 code jumps back and forth between A32 (normal Arm code) and T32 (Thumb code) all the time. having the lowest bit of the function address mark whether it's Thumb is such a neat trick

Rust pro tip: if you have a C/C++ dependency for your project that you have to compile in your build script, consider making it into its own crate. Then it can be compiled in parallel to your Rust code, and it won't be recompiled unnecessarily if you need to change something else that has a build script. You can use Cargo “workspaces” to keep it in the same repo as your main crate.

thank you to whoever it was that added this helpful text to ld's vtable linker error message…

“NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.”
