Taylor Yu 6e7daacb89 feature: add advanced_errs1 
New section and exercise to demonstrate the `From` trait for errors
and its usefulness with the `?` operator.
 2021-06-25 16:55:08 -05:00
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.

fix(variables5): confine the answer further
 2021-06-24 14:10:02 +02:00
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.

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.

Taylor Yu 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.

fix: move_semantics5 hints
 2021-05-23 15:41:56 +02:00
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.

Add hints about how to return the correct type for functions that
return `Result<_, Box<dyn Error>`. Some feedback from Discord suggests
that people run into trouble with that.
