Rust libz blitz!

I’ve also reviewed the state of the env_logger evaluation, trying to move it toward a close. There are a few questions about whether to expand its flexibility or not that need some feedback from the log maintainers before we move forward.

I removed some unimportant mentions so hopefully everybody can edit again.

I opened up the mio evaluation for two weeks from now.

Hi the cookbook repo has been moved to :tada:!

With rendered version available under and repo to

Please note that only some of the old links are still functional due to github redirects, so it’s a good moment to update your bookmarks :slight_smile:

Status update 2017-08-08

This update covers the period from 7/14 to 8/8.

There are several ongoing evaluations:

Thanks to everyone who has been pushing these evaluations forward, and special thanks to @KodrAus and @dtolnay for their help coordinating the effort overall.

Next up is rayon, and a possible out-of-band evaluation for Diesel!

Overall check-in

We took some time to check in on how all of the evaluated crates are doing, and found that in general, things are in fantastic shape. Many crates are essentially complete and ready to cut a 1.0. Others need a final pass over documentation and cookbook examples, but are otherwise ready. Only a few still need significant work:

The libs team hopes to write up detailed contribution guides for the upcoming impl period.

Work completed this cycle

Here’s what happened on crates since the last status report:





Small correction: These were just rebased from work @jeremielate did :slight_smile:

Hi, please do not forget about the work done by rust-cookbook contributors :slight_smile:.

This was a fruitful period. Thanks to all involved!



Hi can anyone with rust-lang-nursery rights enable appveyor for rust-cookbook?

I’d like to add windows ci but being collaborator but not organization member makes me short on foo here :slight_smile:

Please note that enabling under rust-lang-libs instead of nursery domain will not work ok due to weird appveyor permissions making me unable to start builds (We’ve already tried that with Alex earlier this week :confused:)

EDIT: Already done thanks to @alexcrichton! :heart:

I’ve added a link to the tracking issue for env_logger and mio to the OP

Rayon is coming up for the meeting next week – are we as authors supposed to prepare anything? I thought that some external person is supposed to do a review beforehand, but I haven’t seen that.

Could we please get the topic for rayon turned into a wiki? Thanks! :slight_smile:

Gah oops, done now!


The Rayon in-person evaluation has now been done and there’s a tracking issue for rayon work items!

Status update 2017-09-08

This update covers the period from 8/8 to 9/8.

Overall check-in

We’ve finished up the in-band evaluations for the libz blitz this year, but there are still many contribution opportunities for fixing issues raised in the various crates.

There are also still a number of out-of-band evaluations that need people to take on the lead. If you’d like to get on board with one of these just leave a comment here and we can help you get started.

There are a few larger pieces of on-going work to finalise:

  • RFC for the rand API overhaul
  • Issue for merging the tempfile and tempdir APIs

Work completed this cycle

Here’s what happened on crates since the last status report:









If I’ve missed anything out please let me know and I’ll add them to the list!


One contribution to the cookbook was left out :wink:

The last few weeks were quite dry in terms of the cookbook contribution. Mostly due to small number of example ideas (I haven’t had much free time lately). I would like to welcome everyone to contribute the ideas!

On somewhat related news. A new version of cookbook has been deployed incorporating some changes to the presentation that we’ve been working on in mdbook.

  • play button working with crates currently active in play.rlo - (thanks to @shepmaster all libz’blitz crates are available! :tada:)
  • several fixes in mobile browser usability
  • clipboard support

Please checkout the current state of affairs and give your thoughts!

I’ve just started up the evaluation for the num_cpus crate. Check the topic here for more info. This is a nice small crate, perfect for new contributors as well as Rust veterans; great starting point for anyone wanting to get involved with the Rust community :slight_smile:
