fix(errors6.rs): remove one answer code
Although marked as 'TODO', three tests pass without any implementation because the correct answer code already exists.

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.

Taylor Yu 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.

The previous test would stop comparing elements in array a and vec v upon reaching the last element of either. This resulted in the test passing even if v did not contain all the elements in a. This change to the test fixes that bug and should only pass if all the elements in a and v are present and equal.
