In the exercise guideline for the Luhn's algorithm (Day 1, Afternoon
exercise), I made a correction to step 3 to provide a more accurate
explanation. Instead of stating that doubling 7 becomes 14, I clarified
that doubling 7 results in 14, and we should sum the individual digits
of 14 to get the correct value of 5.
Hello there 👋 I'm the author of the `tokio-websockets` crate and
today we published version `0.4.0` of the crate, which finally makes the
public API consistent and aligns it with expectations.
`WebsocketStream` now implements the `Stream` trait, so calling `next()`
has to be done via `StreamExt` now. `connect()` returns a tuple of
`(WebsocketStream, Response)`, so that has to be deconstructed now. And
finally, `as_text()` now returns an `Option<&str>` instead of
`Result<&str, Error>`.
And, *very* importantly: The old `WebsocketStream::next` was **not**
cancellation safe, the new `Stream` implementation is. The exercise uses
`select!`, which very well might have caused misbehavior.
Since we also emptied the default features, I've added the very minimal
ones required to compile the exercise.
This is my first contribution here, so feel free to point me to some
things if I'm missing anything. I wasn't really sure what to do about
the translations, I guess I should leave them as is and they'll be
updated by translators in other PRs?

Adding this test case to handle case where we have non-numeric cc number
along with a valid cc number. This is discovered when we filter with
is_numeric() instead of !is_whitespace() all test case does pass. To
handle such scenario adding this test case.
Hi all!
This CL fixes#1093:
* Avoids including current false-positives in the checking of typos
* Excludes localization-related files, as `typos` works with
English words
* Fixes existing typos caught in the repo
Tested this in CI with a typo and it showed up in the list of actions!

- Morning of Day 1 still introduces the language and its high-level
goals/value proposition, and starts with the built-in data types Rust
provides, and how you define a function.
- Afternoon of Day 1 gets a front loading of the basic control flow
structures in Rust but not the more exotic ones.
- The exercises for day 1 afternoon will be the Luhn algorithm (where we
can match on digits and enums such as `Option`.
- Morning of day 2 still has discussion of memory management.
Fixes#510.

Drops the comment about usage in the other loop. It's not related to the
focus on copy semantics, and so we want to eliminate that possible
confusion.

* Align dining-philosophers-async.rs with sync version
This updates the version to use `std::mem::swap` like the synchronous version.
* Apply suggestions from code review
* Fix solution in Link Checker in Concurrency Morning exercises.
This change fixes the following issues with the current solution:
1. It is not listed on the "solutions" page.
2. It is not multi-threaded and does not use channels.

* exercises: health-statistics: weight -> height
weight may be a sensitive topic for some readers; use height instead as this isn't important to the content of the course
* exercises: health-statistics: add health report
this lets us see a non-setter use case for &mut self
it also makes the 'statistics' side of this exercise more explicit as we count doctor visits
* exercises: health-statistics: normalize variable names
* remove $ from code blocks in translations
* remove $ from code blocks in the other markdown files as well
* Revert "remove $ from code blocks in the other markdown files as well"
This reverts commit eda922dab9.
* remove $ from code blocks in setup.md
* re-added the previous changes
* revert logging.md
Outlines an alternative implementation for Polygon::length. This exercise is aimed at novice users and we want to keep the implementation simple. For users familiar with iterator concepts this comment points to an alternative.
rename 'designing a library' example
library design in Rust is its own topic that this course does not cover; to avoid confusion, let's stick to describing things in terms of books
Clarify that each philosopher should think/eat 100 times.
Folks who have hazy memories of the philosopher dining problem may
interpret the original instructions as "make each philosopher think and
eat once". This interpretation loses a critical detail, because the
resulting code is highly unlikely to deadlock in practice, even without
breaking the symmetry.
* Suggest to run day 3 afternoon exercise locally
Based on feedback from running the class, students found developing
the day 3 afternoon exercise locally was a better experience than
using Playground.
* Update src/exercises/day-3/afternoon.md

* Run builds on both Mac OS and Linux
This would have helped us catch #570.
* Fix MacOS CI (#848)
* Revert unnecessary changes
The changes might be good, but I want to keep this PR small and
focused. If we end up with the extra `cfg` statements, we should
include a comment to let students know what they do: we’re targeting
people new to Rust, so we need to be careful with explanations.

* Adds a description of the async chat exercise
* Simplifies the use of Error in chat-async
* Links the solution to the async chat exercise
* Removes the elevator exercise
* Adds dining philosophers as an async exercise
* Adds a solution for async dining philosophers
* Adds a solution page for the afternoon session on concurrency
* Align outline with new spin-off course structure
With the new structure, the section on Android is a spin-off course
from the main 3-day course on Rust Fundamentals. The Bare-metal and
Concurrency days are spin-off courses in the same way.
* Explain new course structure
* Align Bare-Metal welcome page with other deep dives
* Merge Day 4 page into Course Structure page
* Remove Day 4 Welcome page
This aligns the Concurrency in Rust section with the Bare-Metal Rust
deep dive.
* Show subsections for Android deep dive
This aligns the Rust in Android section with the other deep dives.
* Clean up welcome page and README
We now cover async Rust and the course is no longer a four day course.
* Remove reference to the old Day 4
* Remove Day 4 references from exercises
* Add some more hints to the bare-metal RTC exercise
I and several others had some difficulties with this part of the problem, especially with regards to knowing where the RTC was wired up and how to fully enable the GIC / interrupts, so add this information to the exercise.
* Remove extra semicolon.

* Add methods to mask and clear interrupts.
* Start on GICv3 driver.
* Enable and use RTC interrupt.
* WFI
* Add newtype for interrupt ID.
* Add extension to use interrupt.
* Add method to send an SGI.
* Silence warnings about unused methods in provided drivers.
* Implement Debug manually for IntId.
It's useful to say what kind of interrupt it is.
* Acknowledge and log interrupt.
We should end it as well, but doing so results in a loop unless we first
clear the match.
* cargo fmt with imports_granularity = "module"
* Use arm-gic crate rather than including driver in the example.
* beginning of an Async section
* address review comments
* Add futures page (#497)
NOTE: `mdbook test` does not allow code samples to reference other crates, so
they must be marked as `compile_fail`; see #175.
* Add Runtimes & Tasks (#522)
These concepts are closely related, and there's not much else to know
about runtimes other than "they exist".
This removes the bit about futures being "inert" because it doesn't
really lead anywhere.
* Async chapter (#524)
* Add async channels chapter
* Async control flow

* Remove the "Daemon" slide, as it largely duplicates the "Tasks" slide.
The introduction to the "Control Flow" section mentions tasks as a
kind of control flow.
* Reorganize the structure in SUMMARY.md to correspond to the directory
structure.
* Simplify the "Pin" and "Blocking the Executor" slides with steps in
the speaker notes to demonstrate / fix the issues.
* Rename "join_all" to "Join".
* Simplify some code samples to shorten them, and to print output rather
than asserting.
* Clarify speaker notes and include more "Try.." suggestions.
* Be consistent about where `async` blocks are introduced (in the
"Tasks" slide).
* Explain `join` and `select` in prose.
* Fix formatting of section-header slides.
* Add a note on async trait (#558)
