If you'd like to dig deeper, here are some links: - cargo-semver-checks: https://github.com/obi1kenobi/cargo-semver-checks - Trustfall query engine, which powers cargo-semver-checks: https://github.com/obi1kenobi/trustfall - Trustfall playground, where you can query Rust library APIs in your browser -- for example, "which structs in `itertools` are importable by more than one path": https://play.predr.ag/rustdoc#?f=2&q=*3-Structs-importable-f... - 10min conference talk on Trustfall: https://www.hytradboi.com/2022/how-to-query-almost-everythin... I'm also giving a talk at P99 CONF in a few months about how Trustfall's new optimizations API made cargo-semver-checks over 2300x faster: https://twitter.com/PredragGruevski/status/16893002495908003...

SQL really sucks. In general I'm not a fan of SQL-like syntax since it makes queries with lots of joins really difficult to read -- it's hard to keep track which value came from where. GraphQL has some neat ideas and I really love the clarity the nesting provides. But GraphQL is also too limiting: it can't express arbitrary filters, recursion, optional edges (i.e. left joins), etc. My own take on this is an embeddable GraphQL-like language with all those features and with strong guarantees about execution performance. I've been calling it Trustfall, and you can play around with it (or check out example queries over HN data) in your browser here: https://play.predr.ag/ For example, here's the query "Find the GitHub or Twitter accounts listed in the bios of HN users that comment on HN stories pointing to Open AI's website": https://play.pre
