_This is my response to the [call for 2019 roadmap blog posts][rust2019]
|
|||
|
|
proposing goals and directions for 2019 and future editions. See also [Read
|
|||
|
|
Rust][readrust], where I've collected all the #Rust2019 posts._
|
|||
|
|
|
|||
|
|
2018 was a very busy year for the Rust project. A new edition was released,
|
|||
|
|
progress on stabilising Rust's asynchronous I/O story was made, a new website
|
|||
|
|
was launched, and so much more! In 2019 I'd like to see the language and
|
|||
|
|
wider crates community become more sustainable, address some common gothca's
|
|||
|
|
that newcomers experience, and promote more platforms/architectures to tier 1
|
|||
|
|
status.
|
|||
|
|
|
|||
|
|
## 2018 Retrospective
|
|||
|
|
|
|||
|
|
Before diving into 2019 goals I think it's worth tracking how the project went
|
|||
|
|
on my ideas from [last year][rust2018]:
|
|||
|
|
|
|||
|
|
1. Become a better option for building network daemons and HTTP
|
|||
|
|
micro-services.
|
|||
|
|
1. Continue to improve the discoverability and approachability of crates and
|
|||
|
|
Rust's web presence in general.
|
|||
|
|
1. Gain wider, more diverse tier-1 platform support (especially on servers).
|
|||
|
|
1. Start delivering on the prospect of safer system components, with fewer
|
|||
|
|
security holes.
|
|||
|
|
|
|||
|
|
### Network Services
|
|||
|
|
|
|||
|
|
A lot of progress was made on [Futures] async/await in 2018. The keywords were
|
|||
|
|
reserved in the 2018 edition but are not yet usable on a stable release. [Are
|
|||
|
|
we async yet?][areweasyncyet] shows there's still some work to do. [Hyper] saw
|
|||
|
|
more major changes to keep up with the Futures work and added HTTP/2 support!
|
|||
|
|
|
|||
|
|
### Improve Rust's Web Presence
|
|||
|
|
|
|||
|
|
The Rust web presence was improved with the release of the new website and
|
|||
|
|
blog. The rest of the ecosystem remains much the same. Content from crates.io
|
|||
|
|
is still largely invisible to non-Google search engines such as
|
|||
|
|
[DuckDuckGo][ddg-results] (my primary web search tool), and Bing. The [Rust
|
|||
|
|
Cookbook][rust-cookbook] remains in the nursery.
|
|||
|
|
|
|||
|
|
### Platform Support
|
|||
|
|
|
|||
|
|
[Tier 1 platform support][platform-support] remains unchanged from last year.
|
|||
|
|
There were a number Tier 2 additions/promotions.
|
|||
|
|
|
|||
|
|
### System Components and Increased Safety
|
|||
|
|
|
|||
|
|
The oxidisation of [librsvg] continued in 2018 to the point where almost all
|
|||
|
|
the public API is done in terms of Rust. I'm not aware of many other projects
|
|||
|
|
following this path at the moment:

## Rust 2019
|
|||
|
|
|
|||
|
|
In 2019 I'd like to see the Rust community focus on three areas:
|
|||
|
|
|
|||
|
|
1. Sustainable development
|
|||
|
|
1. Make is easier for newcomers to write fast code / don't surprise people
|
|||
|
|
1. More portability
|
|||
|
|
|
|||
|
|
## Sustainable Development
|
|||
|
|
|
|||
|
|
Recently [Murphy Randle](https://twitter.com/splodingsocks) and [Jared
|
|||
|
|
Forsyth](https://twitter.com/jaredforsyth) were discussing the [event-stream
|
|||
|
|
compromise][event-stream] on the Reason Town podcast. Jared commented:
|
|||
|
|
|
|||
|
|
> The problems of having infrastructure that’s based on unpaid labour that has
|
|||
|
|
> a high degree of burnout.

This is a pretty succinct summary of the problem with our industry. Rust hasn't
|
|||
|
|
shied away from tackling hard problems before and taking on the sustainability
|
|||
|
|
of open source doesn't feel out of the question. There's evidence that many of
|
|||
|
|
the folks deeply involved with the Rust project are already feeling the
|
|||
|
|
pressure and we don't want to lose them to burnout. Such as these posts:

|
|||
|
|
|
|||
|
|
Part of this revolves around culture. The Rust community generally values
|
|||
|
|
quality, correctness, performance, and treating each other with respect. I
|
|||
|
|
think it would be possible to make it normal to contribute financially, or
|
|||
|
|
other means (equipment, education) to Rust language and crate developers (where
|
|||
|
|
people are in a position to do so). A simple first step might be allowing for a
|
|||
|
|
donate badge, akin to CI badges to be added to crate meta data and have this
|
|||
|
|
shown on the Crate page.
|
|||

|
Michael Gattozzi covered some similar thoughts in his,
|
|||
|

|

post.

|

|
## Naïve Code Is Fast Code
|
|||
|
|
|
|||
|
|
People hear that Rust is fast and lean, they try it out converting something
|
|||
|
|
from a language they already know and are surprised to find that it's slower
|
|||
|
|
and/or a much larger binary.
|
|||
|
|
|
|||
|
|
There are
|
|||
|
|
[many](https://www.reddit.com/r/rust/comments/adyd9j/why_is_the_rust_version_of_this_fn_60_slower_than/)
|
|||
|
|
[many](https://www.reddit.com/r/rust/comments/aaood3/go_version_of_program_is_40_quicker_than_rust/)
|
|||
|
|
[many](https://www.reddit.com/r/rust/comments/7w3v77/why_is_my_rust_code_100x_slower_than_python/)
|
|||
|
|
[many](https://www.reddit.com/r/rust/comments/aaood3/go_version_of_program_is_40_quicker_than_rust/)
|
|||
|
|
examples of this in the [Rust Reddit][reddit]. Things that frequently seem to
|
|||
|
|
trip newcomers up are:
|
|||
|
|
|
|||
|
|
1. Not compiling with `--release`
|
|||
|
|
1. Stdio locking
|
|||
|
|
1. Binary size
|
|||
|
|
|
|||
|
|
It would be good to apply the [principle of least surprise][pls] here. I think
|
|||
|
|
the current defaults are inspired by the behaviours expected from C/C++
|
|||
|
|
developers, Rust's original target audience. However the Rust audience is now
|
|||
|
|
much wider than that. With that in mind it might worth reevaluating some of
|
|||
|
|
these things in terms of the current audience. These need not require API
|
|||
|
|
changes, perhaps they could be `clippy` lints. Perhaps they could be slight
|
|||
|
|
changes to language. For example, `cargo` currently says:
|
|||
|
|
|
|||
|
|
> `Finished dev [unoptimized + debuginfo] target(s) in 0.11s`
|
|||
|
|
|
|||
|
|
Perhaps a second line could be added that says:
|
|||
|
|
|
|||
|
|
> `Compile with --release for an optimized build`
|
|||
|
|
|
|||
|
|
to help guide people.
|
|||
|
|
|
|||
|
|
## More Tier 1 Platforms
|
|||
|
|
|
|||
|
|
This one is inherited from last year. I do all my server hosting with [FreeBSD]
|
|||
|
|
and up until recently used it as my desktop OS as well. It's not uncommon to
|
|||
|
|
uncover portability bugs or assumptions when using such a platform. Portability
|
|||
|
|
is type of diversity of software. It makes it stronger and useful to more
|
|||
|
|
people.
|
|||
|
|
|
|||
|
|
Rust is already appealing to people because of its portability. I was recently
|
|||
|
|
talking to a veteran developer at the [Melbourne Rust meetup's hack
|
|||
|
|
night][meetup] about what got them into Rust. It was the combination of modern
|
|||
|
|
language features, native binary **and** portability that drew them to Rust.
|
|||
|
|
|
|||
|
|
To this end I'd like to see more platforms and CPU architectures promoted to
|
|||
|
|
tier 1 status. Up until recently one thing that made this difficult was the
|
|||
|
|
lack of hosted CI services with support for anything other than Linux, macOS,
|
|||
|
|
and Windows. Recently two options have become available that make it possible
|
|||
|
|
to test on other systems, such as FreeBSD. There is [Cirrus CI] which includes
|
|||
|
|
a FreeBSD image in their hosted option, as well as the ability to create
|
|||
|
|
custom images. Secondly there is [sr.ht], a completely open source (but hosted)
|
|||
|
|
option that supports a variety of Linux distributions, and FreeBSD, with more
|
|||
|
|
planned.
|
|||
|
|
|
|||
|
|
[Pietro Albini suggested in his
|
|||
|
|
post](https://www.pietroalbini.org/blog/rust-2019-wishlist/) that the Rust
|
|||
|
|
infrastructure team is already planning to start the discussion on CI options.
|
|||
|
|
I think this would be a perfect opportunity to integrate more platforms into
|
|||
|
|
the CI infrastructure:
|
|||
|
|
|
|||
|
|
> One of the biggest one is switching away from Travis CI for the compiler
|
|||
|
|
> repository. In the past year we had countless issues with them (both small
|
|||
|
|
> and big), and that's not acceptable when we're paying (a lot) for it. The
|
|||
|
|
> infra team is already planning to start the discussion on where we should
|
|||
|
|
> migrate in the coming weeks, and we'll involve the whole community in the
|
|||
|
|
> discussion when it happens.
|
|||
|

## Conclusion
|
|||
|
|
|
|||
|
|
After an intense 2018 it sounds like the Rust project needs to focus on making
|
|||
|
|
the project sustainable over time. I'd love to see some improvements to
|
|||
|
|
address issues newcomers often experience and push more platforms to tier
|
|||
|
|
1 status. Rust is still very exciting to me. I can't wait to see what 2019
|
|||
|
|
brings!
