What does HackerNews think of planter?
Generate PlantUML ER diagram textual description from PostgreSQL tables
You can embed plantuml and drawio diagrams in Rust doc comments and have it rendered in the docs, using this crate
https://crates.io/crates/rsdoc
And you can generate plantuml from SQL tables using
https://crates.io/crates/sqlant (this one is a rust port of a go tool, https://github.com/achiku/planter)
And you can embed plantuml in mdbook
I would say, however, PlantUML is less pretty but more general as a tool and there are neat tools to make the diagrams directly from your database schema [0].
Recently I see a lot general statements on HN like "UML is dead" which I think is not the case. Especially in complex, data-heavy projects it's a great way to visualize how things work -- if kept up-to-date and precise.
