diesel VS uom

7. Diesel

Both seem nice. However, both of them rely very heavily on prepared statements. Unfortunately, using prepared statements is a no-go when you use connection poolers like pgbouncer, or in my case AWS RDS proxy. A discussion in Diesel indicates that disel is not going to provide any support for disabling prepared stements (https://github.com/diesel-rs/diesel/discussions/3575), and a discussion on sqlx hints that disabling prepared statements is possible, but I haven't found any documentation or examples for it.

In addition we are experimenting with prebuild versions of diesel-cli that can be installed directly. We have a set of prebuilt binaries here. We are interested in feedback about how the provided binaries work on your platform.

First of all thanks for making this great tool. As it happens I currently toy around with using it for diesel-cli releases. See the WIP PR here. I think diesel-cli is a good example of a tool that depends on system libraries as it needs to link native database drivers, so this new release is welcome. Defining the dependencies seems to allow easily building things on x86_64-unknown-linux-gnu and x86_64-apple-darwin. It seems to pick up everything in the right way there.

I did look at mysql initially. Then I started checking other crates. Diesel is an Object Relation Model (ORM), I'm not yet keen on taking on the complication of learning ORM, I give this crate a pass in the meantime.

I would recommend people look at diesel from Rust for how nice it could be. https://diesel.rs/ Look at the complex queries example. So much more readable and easier to understand.

Most wanted missing features in diesel

There are two problems with using Rust for web servers:

1. The only production-ready Rust web servers require writing async request handlers. Async Rust is not fun.

2. The only good Postgres client library is async: https://crates.io/crates/sqlx

I'm trying to remedy the first problem with https://crates.io/crates/servlin .

Solving the second problem will be another project. I hope someone else does it. There is https://crates.io/crates/diesel but it has the same problem as async Rust: incomprehensible compiler errors.

Lemmy is written in Rust using Actix Web and Diesel.rs.

uom (type-safe zero-cost dimensional analysis) v0.35.0 got released today!

It happened! v0.34.0 (crates.io) has been released.

My hope is to release uom (type-safe zero-cost dimensional analysis) v0.34.0 this week. There have been a huge number of new quantities and units added since v0.33.0.

I have been reviewing lots of PRs recently submitted to add many new units and quantities to uom (type-safe zero-cost dimensional analysis).

I reviewed some PRs to add new units to uom (type-safe zero-cost dimensional analysis) yesterday and am really hoping to make progress on logarithmic units this week. no_std support is slowing down the later.

Working on a PR to uom (type-safe zero-cost dimensional analysis) to support logarithmic units.

A great type system enables things like unit preserving calculations and Formal Methods.

Is it the error messages, or other parts of uom that make it unwieldy to use? Feedback welcome here or as a new issue.

I'm working through reviewing the open PRs for uom (type-safe zero-cost dimensional analysis).
