Emily Toop da599c3a78 Fix broken documentation links. (#775) (#767) r=nalexander
* Fix broken API doc links

Create symlink for latest to point to v0.7.
Group APIs by top version number rather than individual

* Update swift and android version numbers to match Mentats

* Update documentation

* Update top level .gitignore to ignore docs site & metatdata

* Add README to help with building documentation site

* Address review comments @ncalexan

called from other languages.</p>
<p>Functions that are available to other languages in this module are defined as
extern &quot;C&quot; functions which allow them to be layed out correctly for the
platform's C ABI. They all have a <code>#[no_mangle]</code> decorator to ensure
Rust's name mangling is turned off, so that it is easier to link to.</p>
<p>Mentat's FFI contains unsafe code. As it is an interface between foreign code
and native Rust code, Rust cannot guarantee that the types and data that have been passed
to it from another language are present and in the format it is expecting.
This interface is designed to ensure that nothing unsafe passes through this module
and enters Mentat proper</p>
<p>Structs defined with <code>#[repr(C)]</code> are guaranteed to have a layout that is compatible
with the platform's representation in C.</p>
<p>This API passes pointers in two ways, depending on the lifetime of the value and
what value owns it.
Pointers to values that are guaranteed to live beyond the lifetime of the function,
are passed over the FFI as a raw pointer.</p>
<p><code>value as *const Binding</code></p>
<p>Pointers to values that cannot be guaranteed to live beyond the lifetime of the function
are first <code>Box</code>ed so that they live on the heap, and the raw pointer passed this way.</p>
<p><code>Box::into_raw(Box::new(value))</code></p>
<p>The memory for a value that is moved onto the heap before being passed over the FFI
is no longer managed by Rust, but Rust still owns the value. Therefore the pointer
must be returned to Rust in order to be released. To this effect a number of <code>destructor</code>
functions are provided for each Rust value type that is passed, as is a catch all destructor
to release memory for <code>#[repr(C)]</code> values.
The destructors reclaim the memory via <a href="std::boxed::Box">Box</a> and then drop the reference, causing the
memory to be released.</p>
<p>A macro has been provided to make defining destructors easier.</p>
<p><code>define_destructor!(query_builder_destroy, QueryBuilder);</code></p>
<p>Passing a pointer to memory that has already been released will cause Mentat to crash,
so callers have to be careful to ensure they manage their pointers properly.
Failure to call a destructor for a value on the heap will cause a memory leak.</p>
<p>Generally, the functions exposed in this module have a direct mapping to existing Mentat APIs,
in order to keep application logic to a minumum and provide the greatest flexibility
for callers using the interface. However, in some cases a single convenience function
has been provided in order to make the interface easier to use and reduce the number
of calls that have to be made over the FFI to perform a task. An example of this is
<code>store_register_observer</code>, which takes a single native callback function that is then
wrapped inside a Rust closure and added to a <a href="mentat::TxObserver">TxObserver</a> struct. This is then used to
register the observer with the store.</p>
<p>Functions that may fail take an out parameter of type <code>*mut ExternError</code>. In the event the
function fails, information about the error that occured will be stored inside it (and,
typically, a null pointer will be returned). Convenience functions for unpacking a
<code>Result&lt;T, E&gt;</code> as a <code>*mut T</code> while writing any error to the <code>ExternError</code> are provided as
<code>translate_result</code>, <code>translate_opt_result</code> (for <code>Result&lt;Option&lt;T&gt;&gt;</code>) and <code>translate_void_result</code>
(for <code>Result&lt;(), T&gt;</code>). Callers are responsible for freeing the <code>message</code> field of <code>ExternError</code>.</p>

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
