# Workflow to build your docs with oranda (and mdbook)

#
# Note that the "Deploy to Github Pages" step won't run in this mode,

pull_request:
# Whenever something gets pushed to main, update the docs!
# This is great for getting docs changes live without cutting a full release.
#
# Note that if you're using cargo-dist, this will "race" the Release workflow
# that actually builds the Github Release that oranda tries to read (and
# this will almost certainly complete first). As a result you will publish
# docs for the latest commit but the oranda landing page won't know about
# the latest release. The workflow_run trigger below will properly wait for
# cargo-dist, and so this half-published state will only last for ~10 minutes.
#
# If you only want docs to update with releases, disable this, or change it to
# a "release" branch. You can, of course, also manually trigger a workflow run
# when you want the docs to update.

# Whenever a workflow called "Release" completes, update the docs!

# however that Github's UI is wonky when you use workflow_run, and won't

<a name="5.6.1"></a>
## 5.6.1 (2023-09-18)
#### Changed
- Converted all exercises with assertions to test mode.
#### Fixed
- `cow1`: Reverted regression introduced by calling `to_mut` where it
shouldn't have been called, and clarified comment.
- `primitive_types3`: Require at least an array of 100 elements.
- Removed hint comments when no hint exists for the exercise.
- `as_ref_mut`: Fixed a typo in a test function name.
- `enums3`: Fixed formatting with `rustfmt`.
<a name="5.6.0"></a>
## 5.6.0 (2023-09-04)
#### Added
- New exercise: `if3`, teaching the user about `if let` statements.
- `hashmaps2`: Added an extra test function to check if the amount of fruits is higher than zero.
- `enums3`: Added a test for `Message`.
- `if1`: Added a test case to check equal values.
- `if3`: Added a note specifying that there are no test changes needed.
#### Changed
- Swapped the order of threads and smart pointer exercises.
- Rewrote the CLI to use `clap` - it's matured much since we switched to `argh` :)
- `structs3`: Switched from i32 to u32.
- `move_semantics`: Switched 1-4 to tests, and rewrote them to be way simpler, while still teaching about the same
concepts.
#### Fixed
- `iterators5`:
- Removed an outdated part of the hint.
- Renamed variables to use snake_case.
- `vecs2`: Updated the hint to reference the renamed loop variable.
- `enums3`: Changed message string in test so that it gets properly tested.
- `strings2`: Corrected line number in hint, then removed it (this both happened as part of this release cycle).
- `primitive_types4`: Updated hint to the correct ending index.
- `quiz1`: Removed duplicated sentence from exercise comments.
- `errors4`: Improved comment.
- `from_into`: Fixed test values.
- `cow1`: Added `.to_mut()` to distinguish from the previous test case.
- `threads2`: Updated hint text to reference the correct book heading.
#### Housekeeping
- Cleaned up the explanation paragraphs at the start of each exercise.
- Lots of Nix housekeeping that I don't feel qualified to write about!
- Improved CI workflows, we're now testing on multiple platforms at once.

In the first function we are looping over the Vector and getting a reference to one `element` at a time.
To modify the value of that `element` we need to use the * dereference operator. You can learn more in this chapter of the Rust book:
https://doc.rust-lang.org/stable/book/ch08-01-vectors.html#iterating-over-the-values-in-a-vector
Hint 1: In the code, the variable `element` represents an item from the Vec as it is being iterated.
Can you try multiplying this?
In the second function this dereferencing is not necessary, because the map function expects the new value to be returned.
Hint 2: For the first function, there's a way to directly access the numbers stored
in the Vec, using the * dereference operator. You can both access and write to the
number that way.
