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	50ab289da6	fix: rename result1 to errors4 ... Also put it in the ERROR HANDLING section where it probably belongs.	2021-06-06 23:08:54 -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

k12ish	b4de659438	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.	2021-04-20 11:18:05 +02:00
Pete Pavlovski	72aaa15e6a	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.	2021-04-20 11:15:49 +02:00

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!()`.	2021-04-04 12:41:32 -05:00
