Update options1.rs 
Added extra test for before 10PM and updated the test for at 10PM (when it's 10PM there should already not be any ice cream left, as per the description). Also fixed the `raw_value` test, as it is later than 10PM, so there should be no more ice cream left.

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.

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.

fix(variables5): confine the answer further 
let mut number = 3; can lead to a correct answer, so the comment helps to direct the users to the intended answer.

68d3ac567c feature: improve error_handling exercises 
Add new exercises errors5 and errors6, to introduce boxed errors and
custom error enums more gently. Delete errorsn, because it tried to do
too much too soon.

50ab289da6 fix: rename result1 to errors4 
Also put it in the ERROR HANDLING section where it probably belongs.

91fc9e3118 fix(iterators5): derive Clone, Copy 
To allow more flexibility in solutions, derive `Clone` and `Copy`
for `Progress`.

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.
