arlecchino	34ea029df8	chore: Update hint of iterators3 ... `collect()` needs some hint for standard_library_types/iterators3 exercise with doc link for understanding different return types via `FromIterator`.	2021-06-29 12:03:18 +02:00
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.	2021-06-24 21:33:41 -05:00
marisa	a3ea37b76e	Merge pull request #771 from tlyu/iterators5-trait-tweak ... fix(iterators5): derive Clone, Copy	2021-06-24 14:17:05 +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.	2021-06-09 23:27:53 -05:00
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.	2021-06-06 23:08:57 -05:00

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.	2021-05-22 22:09:58 -05:00

Taylor Yu	11d2cf0d60	fix(try_from_into, from_str): hints for dyn Error ... 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.	2021-05-15 14:01:17 -05:00
