|
|
<ul>
|
|
|
|
|
|
<li>Greatly improved documentation, especially around platform-specific behaviours;</li>
|
|
|
|
|
|
<li>Improved test suite by building our own library to test against;</li>
|
|
|
|
|
|
<li>All <code>Library</code>-ies now implement <code>Send</code>.</li>
|
|
|
|
|
|
<li>Added <code>impl From<os::platform::Library> for Library</code> and <code>impl From<Library> for os::platform::Library</code> allowing wrapping and extracting the platform-specific library handle;</li>
|
|
|
|
|
|
<li>Added methods to wrap (<code>Symbol::from_raw</code>) and unwrap (<code>Symbol::into_raw</code>) the safe <code>Symbol</code>
|
|
|
|
|
|
wrapper into unsafe <code>os::platform::Symbol</code>.</li>
|
|
|
|
|
|
</ul>
|
|
|
|
|
|
<p>The last two additions focus on not restricting potential usecases of this library, allowing
|
|
|
|
|
|
users of the library to circumvent safety checks if need be.</p>

|
|
|
|
|
<h2 id="breaking-changes" class="section-header"><a href="#breaking-changes">Breaking Changes</a></h2>
|
|
|
|
|
|
<p><code>Library::new</code> defaults to <code>RTLD_NOW</code> instead of <code>RTLD_LAZY</code> on UNIX for more consistent
|
|
|
|
|
|
cross-platform behaviour. If a library loaded with <code>Library::new</code> had any linking errors, but
|
|
|
|
|
|
unresolved references weren’t forced to be resolved, the library would’ve “just worked”,
|
|
|
|
|
|
whereas now the call to <code>Library::new</code> will return an error signifying presence of such error.</p>
|
|
|
|
|
|
<h2 id="osplatform" class="section-header"><a href="#osplatform">os::platform</a></h2>
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
<li>Added <code>os::unix::Library::open</code> which allows specifying arbitrary flags (e.g. <code>RTLD_LAZY</code>);</li>
|
|
|
|
|
|
<li>Added <code>os::windows::Library::get_ordinal</code> which allows finding a function or variable by its
|
|
|
|
|
|
ordinal number;</li>
|
|
|
|
|
|
