Rust Tooling (October 2015)

What tools are available for Rust development?
This talk gives you an overview of ways to help you write better Rust code.

1. Tooling
2. Matthias Endler - Backend Engineer at trivago - Deals with Website Performance - Worked a lot with Python and PHP - Played a bit with Golang - Not a Rust Programmer yet - Likes the ideas of Rust @matthiasendler
3. What I like about… • PHP: Package manager, Community • Python: Syntax, Libraries • Golang: Tooling, Documentation • C: Speed, no overhead
4. What I like about… • PHP: Package manager, Community • Python: Syntax, Libraries • Golang: Tooling, Documentation • C: Speed, no overhead RUST
5. RUST: High level on bare metal
6. Complexity vs Speed • PHP • Python • Golang • Rust • C Faster „Easier“
7. Systems Programming Memory management Error handling Static Typing Compiling …
8. Systems Programming is hard!
9. Fast feedback loops What we need:
10. Fast feedback loops What we need: Awesome tooling How we get it:
11. Fast feedback loops What we need: Awesome tooling How we get it: Well integrated All of them should be
12. IDEs?
13. Visual Studio for Rust
14. IntelliJ with Rust support
15. Atom with Rust packages
16. My tool wishlist Unit testing Package manager Syntax highlighting Formatting Code completion Debugging Code linter Benchmarking Profiling Code coverage
17. My tool wishlist Unit testing: builtin Package manager Syntax highlighting Formatting Code completion Debugging Code linter Benchmarking Profiling Code coverage
18. https://doc.rust-lang.org/book/testing.html Unit testing
19. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting Formatting Code completion Debugging Code linter Benchmarking Profiling Code coverage
20. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting Code completion Debugging Code linter Benchmarking Profiling Code coverage
21. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion Debugging Code linter Benchmarking Profiling Code coverage
22. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging Code linter Benchmarking Profiling Code coverage
23. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter Benchmarking Profiling Code coverage
24. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter: clippy Benchmarking Profiling Code coverage
25. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter: clippy Benchmarking: builtin Profiling Code coverage
26. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter: clippy Benchmarking: builtin Profiling: meh… Code coverage
27. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter: clippy Benchmarking: builtin Profiling: meh… torch? Code coverage

29. My tool wishlist Unit testing: builtin Package manager: cargo Syntax highlighting: atom-language-rust Formatting: rustfmt Code completion: racer Debugging: rust gdb? Code linter: clippy Benchmarking: builtin Profiling: meh… torch? Code coverage: kcov?
30. kcov …is a code coverage tester for compiled programs, Python scripts and shell scripts language: rust matrix: fast_finish: true include: - rust: nightly env: FEATURES="--features nightly" sudo: false - rust: nightly env: FEATURES="--features nightly" BENCH=true sudo: false - rust: beta sudo: true after_success: | sudo apt-get install libcurl4-openssl-dev libelf-dev libdw-dev && wget https://github.com/SimonKagstrom/kcov/archive/master.tar.gz && tar xzf master.tar.gz && mkdir kcov-master/build && cd kcov-master/build && cmake .. && make && sudo make install && cd ../.. && kcov --coveralls-id=$TRAVIS_JOB_ID --exclude-pattern=/.cargo target/kcov target/debug/hyper-* Put this into your .travis.yml:
31. Summary Lots of work to do But impressive start
32. We need to focus on those… Unit testing Package manager Syntax highlighting Formatting Code completion Debugging Code linter Benchmarking Profiling Code coverage
33. Bonus rr - a reverse debugger
 (http://rr-project.org/) Dash - Offline API Documentation browser for Mac (https://kapeli.com/dash) Crates.io reverse package lookup
