Chasing Rabbits is a personal blog at erickt.github.io about programming and systems. Since 2014, 10 different Hacker News readers have linked it 15 times, most often “Using Rust to Make a Safer Interface for Yahoo’s Fast MDBM Database”. The last post was in 2016, but the archive is still widely read.
I’m thrilled to announce Serde 0.7.0! It’s been a long time coming, and has a number of long awaited new features, breaking changes, and …

Here are a few google results: * http://erickt.github.io/blog/2014/11/03/performance/ and http://erickt.github.io/blog/2014/11/11/benchmarks/ * https://github.com/ugorji/go-codec-bench * https://github.com/golang/go/issues/5683 In my own testing it was faster (even with ffjson) to pre-clean my data in cpython or pypy, and then emit some intermediary format (like capnproto) for the go code to consume. I was parsing h…

HN discussionOne of the most important tools when writing unsafe rust is compiletest [1]. It's a tool extracted from the compiler project that lets you write tests that are supposed to fail compilation. Since safe abstractions rely on the type system to make unsafe code safe, it's critical to make sure the compiler is properly rejecting code. I wrote a post about this years ago when I got hit by one of the bugs Gankro wrote abou…

HN discussionAFAIK, rust-bindgen doesn't currently have support for translating C functions and structs into anything other than the same things in Rust. It's somewhat idiomatic for manually-written bindings, layered on top of the generated ones, to take care of things like providing a memory-safe interface (which can't really be done automatically), converting between native Rust types and C representations if necessary (perhap…

HN discussionFun note: Because of this line in the article > Because MDBM gives you raw pointers into the DB’s data, you have to be very careful about making sure you don’t have array over-runs, invalid pointer access, or the like.

HN discussionI’d go further and say it’s not possible to fully implement async/await without compiler help. I got really far with stateful, back in 2016 [1]. Stateful was an attempt to write a coroutine library in a proc macro, which generated state machines, as opposed to using os primitives like green threading. This was back before the rust community really started working in this space. I ended up extracting the type system…
