Bay area peeps -- we're hosting an East Bay #rustlang meetup on the 18th! Come join us in downtown Oakland, steps away from BART :)

Published the design document for how nextest implements records, replays and reruns. It's very large — over 6000 words! Lots of decisions and alternatives considered, to make what I believe is the best implementation of this set of features in the industry. Have a look!

https://nexte.st/docs/design/architecture/recording-runs/

Call for testing: nextest can now rerun failing tests!

cargo nextest self update --version 0.9.123-b.3
# enable functionality, see link
cargo nextest run

If tests fail and/or the run is cancelled, then:

cargo nextest run -R latest

to rebuild and pick up from where the test run left off.

Please test this out!

https://nexte.st/docs/features/record-replay-rerun/

A lot of care went into building replay/rerun functionality in a way that's robust, both in the architecture and in the UX, and I'm excited about your feedback.

Call for testing: cargo nextest 0.9.119-b.2 with pager (like less) support!

Please run `cargo nextest self update --version 0.9.119-b.2`, then try out:

cargo nextest list
cargo nextest show-config test-groups
cargo nextest (without further arguments)
cargo nextest run -h and --help

Thanks!

EDIT: Please update to beta 2 for a bugfix, thanks :)

Released cargo-nextest 0.9.117 with experimental support for running benchmarks from within nextest, via `cargo nextest bench`.

Why use this instead of cargo bench? In case you want to benefit from nextest's features, such as per-test isolation, setup scripts, or wrapper scripts.

new #rustlang crate drop: iddqd! ID-based maps where keys are borrowed from values. Four maps are included: IdOrdMap, IdHashMap, a bijective (1:1) BiHashMap and a trijective (1:1:1) TriHashMap.

At Oxide we've found this pattern to be extraordinarily useful. iddqd is no-std compatible, too!
