Taylor Yu abd6b70c72 feat: add advanced_errs2 
New exercise to demonstrate traits that make it easier for other code
to consume our custom error types.
 2021-09-25 11:18:23 +02:00
Taylor Yu 882d535ba8 feat: add advanced_errs1 
New section and exercise to demonstrate the `From` trait for errors
and its usefulness with the `?` operator.

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`.

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 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.

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.

Dylan Nugent 5b1e673cec fix(primitive_types4): Fail on a slice covering the wrong area 
This commit converts primitive_types4 to a test and asserts that the
slice given is equal to the expected slice.

The intent of the primitive_types4 exercise appears to be to ensure the
user understands inclusive and exclusive bounds as well as slice syntax.
`rustlings` commands using `compile` do not verify that a specific
println is reached and, in the case of `watch` and `verify` (but not
`run`), they do not output the `println`s at all.

This fix is semantically similar to #198. It does not take a stance on
the correct way to handle this for all exercises; see #127. There are
likely other exercises whose intent are masked by this issue.
