## 5.0.0 (2022-07-16)
|
||||
|
||||
#### Features
|
||||
|
||||
- Hint comments in exercises now also include a reference to the
|
||||
`hint` watch mode subcommand.
|
||||
- **intro1**: Added more hints to point the user to the source file.
|
||||
- **variables**: Switched variables3 and variables4.
|
||||
- Moved `vec` and `primitive_types` exercises before `move_semantics`.
|
||||
- Renamed `vec` to `vecs` to be more in line with the naming in general.
|
||||
- Split up the `collections` exercises in their own folders.
|
||||
- **vec2**: Added a second part of the function that provides an alternative,
|
||||
immutable way of modifying vec values.
|
||||
- **enums3**: Added a hint.
|
||||
- Moved `strings` before `modules`.
|
||||
- Added a `strings3` exercise to teach modifying strings.
|
||||
- Added a `hashmaps3` exercise for some advanced usage of hashmaps.
|
||||
- Moved the original `quiz2` to be `strings4`, since it only tested strings
|
||||
anyways.
|
||||
- Reworked `quiz2` into a new exercise that tests more chapters.
|
||||
- Renamed `option` to `options`.
|
||||
- **options1**: Rewrote parts of the exercise to remove the weird array
|
||||
iteration stuff.
|
||||
- Moved `generics3` to be `quiz3`.
|
||||
- Moved box/arc exercises behind `iterators`.
|
||||
- **iterators4**: Added a test for factorials of zero.
|
||||
- Split `threads1` between two exercises, the first one focusing more on
|
||||
`JoinHandle`s.
|
||||
- Added a `threads3` exercises that uses `std::sync::mpsc`.
|
||||
- Added a `clippy3` exercises with some more interesting checks.
|
||||
- **as_ref_mut**: Added a section that actually tests `AsMut`.
|
||||
- Added 3 new lifetimes exercises.
|
||||
- Added 3 new traits exercises.
|
||||
|
||||
#### Bug Fixes
|
||||
|
||||
- **variables2**: Made output messages more verbose.
|
||||
- **variables5**: Added a nudging hint about shadowing.
|
||||
- **variables6**: Fixed link to book.
|
||||
- **functions**: Clarified the README wording. Generally cleaned up
|
||||
some hints and added some extra comments.
|
||||
- **if2**: Renamed function name to `foo_if_fizz`.
|
||||
- **move_semantics**: Clarified some hints.
|
||||
- **quiz1**: Renamed the function name to be more verbose.
|
||||
- **structs1**: Use an integer type instead of strings. Renamed "unit structs"
|
||||
to "unit-like structs", as is used in the book.
|
||||
- **structs3**: Added the `panic!` statement in from the beginning.
|
||||
- **errors1**: Use `is_empty()` instead of `len() > 0`
|
||||
- **errors3**: Improved the hint.
|
||||
- **errors5**: Improved exercise instructions and the hint.
|
||||
- **errors6**: Provided the skeleton of one of the functions that's supposed
|
||||
to be implemented.
|
||||
- **iterators3**: Inserted `todo!` into `divide()` to keep a compiler error
|
||||
from happening.
|
||||
- **from_str**: Added a hint comment about string error message conversion with
|
||||
`Box<dyn Error>`.
|
||||
- **try_from_into**: Fixed the function name in comment.
|
||||
|
||||
#### Removed
|
||||
|
||||
- Removed the legacy LSP feature that was using `mod.rs` files.
|
||||
- Removed `quiz4`.
|
||||
- Removed `advanced_errs`. These were the last exercises in the recommended
|
||||
order, and I've always felt like they didn't quite fit in with the mostly
|
||||
simple, book-following style we've had in Rustlings.
|
||||
|
||||
#### Housekeeping
|
||||
|
||||
- Added missing exercises to the book index.
|
||||
- Updated spacing in Cargo.toml.
|
||||
- Added a GitHub actions config so that tests run on every PR/commit.
