PostgreSQL Logical Replication Explained
For C there should be good options.
For Rust it doesn't appear that well-supported.
A very simple approach is to poll for changes using `pg_logical_slot_get_changes()` - that should work with any driver. That's what I used for my initial experimentation, before switching over to the streaming replication protocol for better performance.
The streaming replication protocol is not that complicated, but currently you'll have to handle some of the low-level protocol yourself, or work with some very experimental implementations. There's a project to help get you started at [1], and some more discussion at [2].
For the logical decoder, wal2json is quite nice to experiment with, but I've found pgoutput is not that complicated and gives you something closer to the raw data.

Reviews of the Diesel ORM, are there better alternatives?
I can understand that this can be frustrating and I know that the situation there is not ideal for diesel. There are certainly things to improve there by either providing a bundling support which builds the native library as part of the normal build process or by implementing a pure rust connection implementation. Both is possible with diesel, but requires some work. At least the pure rust connection implementation is something that can be provided by a third party crate now with upcoming diesel 2.0 release. If you are interested in that checkout this and this issue. As for the bundling support: This requires changes in the mysqlclient-sys and pq-sys crates. Again help there is welcome. In the end it makes me sad that some people have repeating decided that a solution to this problem is to write just another crate instead of helping to fix these issues. This just results in everyone have more work to do, as there are now two non-perfect solutions instead of having one slightly improved solution.

GitHub - tzConnectBerlin/rust-pg_bigdecimal: A Rust native datatype for Postgres' Numeric type, to be used with Rust's "Postgres" library.
We created this little library to have a fully native type for Postgres Numerics with the rust-postgres (https://github.com/sfackler/rust-postgres) library.

pigeon-rs: Open source email automation written in Rust
The problem with a crate like postgres is that you have to define the types of the query at compile-time. And if you use the simple query protocol in postgres, you just get a bunch of strings, i.e. no proper typing at all. However, for maximal flexibility arbitrary queries should work in pigeon, without knowing the database schema.

Announcing Usual -- a small nORM wrapper to make dealing with SQL easier (like tokio-postgres)
Some nifty things about usual: - It's a generic wrapper over any SQL "row" object. The first implementation that's provided is for tokio-postgres, but traits are available to implement over whatever you'd like. - It provides static typing for partial queries. That is, it supports fetching a subset of fields from a row and makes a unique type for the return value. This gives you some neat-o type safety like this:

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

Learning Rust: Structuring Data with Structs
Another week, another dive into Rust. This time, we're delving into structs. Structs bear resemblance to interfaces in TypeScript, enabling the grouping of intricate data sets within an object, much like TypeScript/JavaScript. Rust also accommodates functions within these structs, offering a semblance of classes, albeit with distinctions. Let's delve into this topic.

Algorithms for Modern Hardware
There’s also other reasons. For example, take binary search:
* prefetch + cmov. These should be part of the STL but languages and compilers struggle to emit the cmov properly (Rust’s been broken for 6 years: https://github.com/rust-lang/rust/issues/53823). Prefetch is an interesting one because while you do optimize the binary search in a micro benchmark, you’re potentially putting extra pressure on the cache with “garbage” data which means it’s a greedy optimization that might hurt surrounding code. Probably should have separate implementations as binary search isn’t necessarily always in the hot path.
* Eytzinger layout has additional limitations that are often not discussed when pointing out “hey this is faster”. Adding elements is non-trivial since you first have to add + sort (as you would for binary search) and then rebuild a new parallel eytzinger layout from scratch (i.e. you’d have it be an index of pointers rather than the values themselves which adds memory overhead + indirection for the comparisons). You can’t find the “insertion” position for non-existent elements which means it can’t be used for std::lower_bound (i.e. if the element doesn’t exist, you just get None back instead of Err(position where it can be slotted in to maintain order).
Basically, optimizations can sometimes rely on changing the problem domain so that you can trade off features of the algorithm against the runtime. These kinds of algorithms can be a bad fit for a standard library which aims to be a toolbox of “good enough” algorithms and data structures for problems that appear very very frequently. Or they could be part of the standard library toolkit just under a different name but you also have to balance that against maintenance concerns.
