<h4>Features</h4>

<h4>Bug Fixes</h4>
|
||
|
|
<ul>
|
||
|
|
<li><strong>variables2</strong>: Made output messages more verbose.</li>
|
||
|
|
<li><strong>variables5</strong>: Added a nudging hint about shadowing.</li>
|
||
|
|
<li><strong>variables6</strong>: Fixed link to book.</li>
|
||
|
|
<li><strong>functions</strong>: Clarified the README wording. Generally cleaned up
|
||
|
|
some hints and added some extra comments.</li>
|
||
|
|
<li><strong>if2</strong>: Renamed function name to <code>foo_if_fizz</code>.</li>
|
||
|
|
<li><strong>move_semantics</strong>: Clarified some hints.</li>
|
||
|
|
<li><strong>quiz1</strong>: Renamed the function name to be more verbose.</li>
|
||
|
|
<li><strong>structs1</strong>: Use an integer type instead of strings. Renamed "unit structs"
|
||
|
|
to "unit-like structs", as is used in the book.</li>
|
||
|
|
<li><strong>structs3</strong>: Added the <code>panic!</code> statement in from the beginning.</li>
|
||
|
|
<li><strong>errors1</strong>: Use <code>is_empty()</code> instead of <code>len() > 0</code></li>
|
||
|
|
<li><strong>errors3</strong>: Improved the hint.</li>
|
||
|
|
<li><strong>errors5</strong>: Improved exercise instructions and the hint.</li>
|
||
|
|
<li><strong>errors6</strong>: Provided the skeleton of one of the functions that's supposed
|
||
|
|
to be implemented.</li>
|
||
|
|
<li><strong>iterators3</strong>: Inserted <code>todo!</code> into <code>divide()</code> to keep a compiler error
|
||
|
|
from happening.</li>
|
||
|
|
<li><strong>from_str</strong>: Added a hint comment about string error message conversion with
|
||
|
|
<code>Box<dyn Error></code>.</li>
|
||
|
|
<li><strong>try_from_into</strong>: Fixed the function name in comment.</li>
|
||
|
|
</ul>
|
||
|
|
<h4>Removed</h4>
|
||
|
|
<ul>
|
||
|
|
<li>Removed the legacy LSP feature that was using <code>mod.rs</code> files.</li>
|
||
|
|
<li>Removed <code>quiz4</code>.</li>
|
||
|
|
<li>Removed <code>advanced_errs</code>. 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.</li>
|
||
|
|
</ul>
|
||
|
|
<h4>Housekeeping</h4>
|
||
|
|
<ul>
|
||
|
|
<li>Added missing exercises to the book index.</li>
|
||
|
|
<li>Updated spacing in Cargo.toml.</li>
|
||
|
|
<li>Added a GitHub actions config so that tests run on every PR/commit.</li>
|
||
|
|
</ul>
