Top 7 Rust Migration Projects

Migrate C code to Rust

Project mention: Converting the Kernel to C++ | news.ycombinator.com | 2024-01-10

A recent practical example of the former: the fish shell re-wrote incrementally from C++ to Rust, and is almost finished https://github.com/fish-shell/fish-shell/discussions/10123
An example of the latter: c2rust, which is a work in progress but is very impressive https://github.com/immunant/c2rust
It currently translates into unsafe Rust, but the strategy is to separate the "compile C to unsafe Rust" steps and the "compile unsafe Rust to safe Rust" steps. As I see it, as it makes the overall task simpler, allows for more user freedom, and makes the latter potentially useful even for non-transpiled code. https://immunant.com/blog/2023/03/lifting/

Project mention: We built our customer data warehouse all on Postgres | news.ycombinator.com | 2024-02-02

Thanks! Yeah definitely agree that building out declarative table management for Postgres would be a major effort. A few open source projects I've seen in that area include:
https://github.com/sqldef/sqldef (Go)
https://github.com/bikeshedder/tusker (Python but being ported to Rust)
https://github.com/tyrchen/renovate (Rust)
https://github.com/blainehansen/postgres_migrator (Rust)
Some of these are based on parsing SQL, and others are based on running the CREATEs in a temporary location and introspecting the result.
The schema export side can be especially tricky for Postgres, since it lacks a built-in equivalent to MySQL's SHOW CREATE TABLE. So most of these declarative pg tools shell out to pg_dump, or require the user to do so. But sqldef actually implements CREATE TABLE dumping in pure Golang if I recall correctly, which is pretty cool.
There's also the question of implementing the table diff logic from scratch, vs shelling out to another tool or using a library. For the latter path, there's a nice blog post from Supabase about how they evaluated the various options: https://supabase.com/blog/supabase-cli#choosing-the-best-dif...
