Latest update from the #eurorust24 YouTube channel! A new video just dropped! Join @predrag as he breaks down advanced Rust testing techniques: invariant testing, snapshot testing, and deterministic simulation. Perfect for anyone ready to catch sneaky bugs and write rock-solid code.

Watch it his talk at EuroRust https://youtu.be/3EFue8PDyic

Also check out Predrag's amazing ‘cargo-semver-checks’ crate and his Trustfall Query Engine https://predr.ag/about/

My "How to Query (Almost) Everything" talk is now also available in written form!

A friend's company uses a bot for GitHub issue triage. They wanted to know how often people react or to its comments.

A few min and one #Trustfall query later, they had a dataframe with all their data: 5000+ rows.

Who else could use this? RTs appreciated, DM me for access

Better autocomplete in Trustfall playground

Contributed by GitHub user u9g, now it only suggests directives that are valid for that spot in the query.

Here only edges can have @​recurse or @​optional, so they aren't offered on properties like byUsername.

Day 2 of P99 CONF is today!

I'll be talking about Trustfall's new optimization API. It massively sped up semver linting in Rust, and it can do the same for your apps too!

Starting to build a Trustfall adapter just got easier:

trustfall_stubgen --schema <file> --target <dir>

High-quality adapter stub containing all types, properties, and edges in your schema. It even unpacks edge properties into their proper types!

All screenshots from the example HackerNews schema in the Trustfall repo's test cases:

Trustfall's new query optimizations API is taking shape

Here's the "how is this vertex being used by this query" portion of the API. Any thoughts? Any better naming ideas?

This P!nk performance of Trustful is amazing.
