macros4.rs: Add rustfmt::skip to prevent auto-fix.
The `macros4.rs` challenge can automatically be solved by rustfmt without the user noticing.

Adding `#[rustfmt::skip]` above the `macro_rules!` line fixes this issue.

1ac66f372b docs: clarify instructions on iterators5.rs

bbdc5c6039 refactor(cow1): replace main with tests
Following the discussion in #1195 this is the best I could come up with.
The issue for me (and apparently a few other learners) was that the code
needed to complete the exercise was not _missing_, but was rather there
but wrong.

In the end, what made the difference between this exercise and others
(for me) was that in this exercise I was supposed to learn what to
*expect* of an output. So I think it makes sense here to let the learner
modify the tests and not the code itself.

Fixes #1195

You can keep working on this exercise,

Update options1.rs

5812f1f27b fix(if2): Rename if2 exercise function to foo_if_fizz.
The reasoning here is pretty straightforward: you don't say "Hungry, if
eat." That doesn't make sense. We want to get "foo" back if given
"fizz", so it seems this makes far more sense as "Eat, if hungry," or in
this case, return `foo_if_fizz` is given.

fix(structs3): Add a hint for panic (#608)
as a totally newbie to Rust, I don't know panic statement from https://doc.rust-lang.org/book/ and rustlings in the beginning. After a hard searching of [should_panic], then I figure out panic statement. 

So it's helpful to tell the learner that write a panic statement here.

d1ee2daf14 fix(structs3.rs): assigned value to cents_per_gram in test

Previous commits (9ca08b8f2b and 114b54cbdb (diff-ce1c232ff0ddaff909351bb84cb5bff423b5b9e04f21fd4db7ffe443e598e174)) removed the mathematical complexity, and I feel this addition is a needed change to further streamline the exercise.

fix(move_semantics5): change &mut *y to &mut x (#814)
Instead of having to explain why 
```rs
let mut x = 100; 
let y = &mut x;
let mut z_owned = *y;
let z = &mut z_owned;
*y += 100;
*z += 1000;
```
and 
```rs
let mut x = 100; 
let y = &mut x;
let z = &mut *y;
*y += 100;
*z += 1000;
```
are different, you still get the point across about having only one mutable reference.
As it stands, this exercise does too much (dereferencing and having only one mutable reference), and by doing so confuses people.

Example of someone being confused by this:

2dc93cadda fix(from_str, try_from_into): custom error types
Remove the use of trait objects as errors from `from_str` and
`try_from_into`; they seem to have caused a lot of confusion in
practice. (Also, it's considered best practice to use custom error
types instead of boxed errors in library code.) Instead, use custom
error enums, and update hints accordingly. Hints also provide
some guidance about converting errors, which could be covered
more completely in a future advanced errors section.

Also move from_str to directly after the similar exercise `from_into`,
for the sake of familiarity when solving.

b7ddd09fab address review feedback
Adjust error text and naming to conform with best practices.
Use `map_err()` instead of `or()`. Wrap lower-level errors instead of
ignoring their details.

Also, don't "cheat" by bypassing the `new()` function in tests.

Fix a dangling reference in the try_from_into hints.

1b85828548 fix: move_semantics5 hints
Improve the hints for move_semantics5, as well as the explanatory
comments in the code.

Previously, it was not clear what possible changes were allowed.
It seems that reordering the statements might be the intended solution.
The previous comment about not "adding newlines" doesn't make sense,
so treating it as "adding new lines" makes it more clear.
