Adam Sherwood 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.

Michael Walsh d1ee2daf14 fix(structs3.rs): assigned value to cents_per_gram in test 
Intended to simplify the lesson by removing the need to figure out what the value is meant to be based on the tests.

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:

Taylor Yu 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.

Taylor Yu 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.

The previous comment about not "adding newlines" doesn't make sense,
so treating it as "adding new lines" makes it more clear.

fix(option2): Rename uninformative variables (#675) 
Renaming uninformative names like `optional_value`, `value`, `optional_values_vec` and `value` helps users distinguish between the two parts of the task.

fix(hashmap2): Update incorrect assertion (#660) 
The test description says "at least five types of fruit", but the test itself is checking for exactly five types of fruit, which was a bit misleading for newcomers like me :) 

A simple change from "==" to ">=" should do the trick and successfully check for the "at least" condition.

Taylor Yu c3e7b83178 fix: use trait objects for from_str 
Use `Box<dyn error::Error>` to allow solutions to use `?` to propagate 
errors.

Taylor Yu 2e93a588e0 fix: use trait objects for try_from_into 
Use `Box<dyn error::Error>` to allow solutions to use `?` to propagate
errors.  In the tests, explicitly check `is_ok()` instead of trying to
force the error type to `String` (or other `PartialEq` type) using
`assert_eq!()`.

chore: clarify collections documentation 
C++ `map` is more like BTreeMap.

`unordered_map` in C++(11) is the equivalent of `HashMap` in Rust.
(+ additional like for references).
