  • Ormlite: An ORM in Rust for developers that love SQL

    Congratulations to the release. I know all of this is hard work. I would like to invite you to submit a ormlite implementation to the diesel benchmark collection. As soon as that's merged you will get regular reports here. The relevant code is here in the diesel repository.

    Doing arbitrary syntax transformations in procedural macros is not powerful enough? Does C++ have something like serde or diesel?

    I've been building a relatively small project with axum and diesel, and I'm pretty happy with it.

    For connecting and performing queries on the db, I prefer diesel.
  • SQL and Rust

    It's not even a libpq issue, but an issue with a specific libpq distribution. You just need to use a not broken version of libpq or ask the vendor of that specific libpq version to fix their binary. See here for a in depth discussion. Calling diesel or libpq to be responsible for this is rather strange.

  • Initial release of diesel-async
    8 projects | reddit.com/r/rust | 27 Sep 2022
    Diesel is a Safe, Extensible ORM and Query Builder for Rust diesel-async is an pure rust fully async connection implementation for Diesel. It provides connection implementations for the Diesel PostgreSQL and MySQL backend. It is designed to be used as drop in replacement for the sync connection implementations in Diesel. diesel-async support almost all the functionality provided by diesel (beside migrations), so it features the same compile time guarantees as Diesel itself. It reuses Diesels query builder infrastructure here.

    We have some benchmarks here in the main diesel repository. Results are tracked here. A short summary is that diesel-async is nearly as fast as diesel itself for those benchmarks. It outperforms other implementation like sqlx and sea-orm. I should also not that I have not put in any effort to optimize the implementation, so it might be possible to get it on par with diesel itself. Otherwise as diesel-async internally use the pure rust database connection implementations and not the c libraries some differences might be attributed to differences in that implementations as well.
