The Error::type_id method was recently stabilized as part of Rust 1.34.0. This point release destabilizes it

So in summary a feature that was stable for 3 days is taken back for further bugfixing. A bit unfortunate but given the very short timeframe where it was stable the impact should be minimal.

The best bugs are short-lived bugs.

In this case I think it's a short-lived feature.

The worst kind of stability is short-lived stability.

A month and 3 days, but yeah.

It seems like such a terribly subtle bug. I wonder, how was it discovered (so quickly)?

Rust releases spend six weeks in beta, and each individual feature can spend an unlimited amount of time baking in nightly, which is usually enough time to catch potential soundness issues before they find their way into stable (this is the second point release that I can recall having such a purpose). The particular feature under which this API falls has been in nightly for quite a while, so it may be that someone had a half-formed idea of how to trigger memory unsafety and was only reminded of it when they read the release notes where its stabilization was mentioned.

It was well known from older versions of GHC Haskell. Given how much Haskell knowledge was imported into Rust, it's surprising that this made it into stable at all.

By the way, does anyone know any success stories of using Rust for writing business logic/software?

We use (and we love!) Rust at https://snips.ai, you can take a look at a recent optimized neural network library we have open-sourced which uses Rust!

We use it for Turtl (https://github.com/turtl/core-rs). I converted a huge portion of the business logic from js -> rust to make it embeddable in a lot of different platforms (by exposing a C api). Very successful, much more stable and fast than its JS ancestor.
