impl Days is a sibling event of RustFest<Paris>, sponsored by
Mozilla and 1aim.
impl Days is an open-ended time for Rust contributors to
collaborate in an active programming session. It will take place on
the two days following the RustFest talks and workshops,
Monday, May 28th and Tuesday, May 29th.
Back at RustFest
Over those two days, 30 to 40 people came together to discuss, design, and implement changes to Rust itself as well its broader ecosystem.
Plus, they got to build a Lego Death Star.
impl Days was such a success that we decided to repeat
the event here in Paris.
The event is being hosted at Mozilla Paris and Formeret Espace Cléry.
impl Days is a great chance to work directly with other Rust
enthusiasts. The Rust project is supported by volunteers across the
globe, and while we often rely on github comments and IRC channels for
communication, the face-to-face communication enabled by an event like
this can be a big productivity boost.
You may be just starting out as a Rust contributor, or you may be a
long-time compiler hacker who reminisces about the days when Rust was
bootstrapped atop ML. Either way, there’s plenty of tasks for all
You do not need to buy a separate ticket for
impl Days; your Rust
Fest ticket will suffice. However, the
impl Days venue,
is more limited in space than the main RustFest venue.
Due to the increased number of interested attendees, we will also have space available at Formeret Espace Cléry at
17, rue de Cléry, 75002 Paris.
It is at 10 minute walk away from the Mozilla Paris office.
Thus, everyone who plans to attend
impl Days should tell us
explicitly on the online questionnaire built into the RustFest ticket.
Felix Klock (pnkfelix) will act as coordinator, striving to aid participants in their efforts to contribute to the Rust language, ecosystem, and community.
Felix requests that participants come to the Mozilla Paris office in
the morning between 9 and 9:30 AM. We will spend some time each
morning getting to know each other, and then identify tasks for
participants to collaborate on. There will be coffee provided at the
venue, and a break for a lunch at noon. Each of the two
will start winding down around 5 PM. All participants must, with heavy
hearts, vacate the Mozilla premises each day by 6 PM.
Of course all participants are free to arrive later and depart earlier than the times specified above.
We anticipate that some participants may even decide partway through the session that exploring the city of Paris is a more attractive way to spend their day than wrestling with Rust’s borrow checker.
For ideas of what kinds of tasks we all might work on, check out the blog post describing Rust’s roadmap for 2018.
(We will make more detailed plans on-the-fly at
impl Days itself,
based on the skill sets of the people who show up to contribute.)
