It's Thursday, day 4. Today's haul so far is ~2500 LoC.

First, making use of default-value stability which we previously exposed in rustdoc JSON. Pairing with Codex on this caught a subtle new edge case that affects which traits are considered sealed.

Copious test cases come standard, of course.

I had to take a brief detour to triage a surprising new class of SemVer breakage.

It's always *a time* when the net result is "8 issues across 5 repos" 😅

The net result is the same: even more lints!

It's Wednesday, day 3.

Default-stability is in rustdoc JSON in today's nightly Rust. Only *stable* defaults are public API, so we pretend unstable values don't exist.

I'm working on a PR for this, and also on type normalization improvements to let us have type-checking lints 👀

Just realized that I have 20+ different version of stable #rustlang toolchain installed. Not as good as `cargo clean`, but freed some space.

My MacBook NEVER has enough disk space. So it’s nice to work with remote datasets over S3 to save space… but except when the bucket is on the other side of the ocean and AWS won’t push bits to my house much faster than 100Mbps 😅

So I set up my own mini S3 on my homelab server!

It's Tuesday, and so far so good!

Two things happened today, by which I mean after midnight last night.

First, I merged a PR to allow unstable stdlib items to be considered non-public-API. Similarly, const-unstable items are considered non-const in public API:

Second, the last required upstream PR got merged into rustdoc!

It lets us know which default values (like on associated consts, or default method impls in traits) are considered stable and therefore public API. This is the last "partial stability" mechanism we need.

Since February, I’m refactoring the Event Cache inside the Matrix Rust SDK. You can view it as a reactive database to store and organise all events for a Matrix client.

https://github.com/matrix-org/matrix-rust-sdk/issues/6152

The code has landed in `main` and the first client to use it is Element X nightly. It works like a charm! It’s impressive how refactoring with Rust is easy and safe (considering all the locks and async we have).

I’m a bit proud of it.

It's Friday again, so it's time for another update on the work on Diesel, a ORM and query builder for Rust.

The news of the week is the release of mysqlclient-src 0.2.2, which improves an error message for incompatible platforms. See the release announcements for details: https://github.com/sgrif/mysqlclient-sys/releases/tag/v0.2.2

This week we received 6 new PR's, no new bug report, but three non-public "security" reports.
