<p>All rust symbols by default are mangled as they contain characters that
cannot be represented in all object files. The mangling mechanism is similar
to C++'s, but Rust has a few specifics to handle items like lifetimes in
symbols.</p>
<p>This function will take a <strong>mangled</strong> symbol (typically acquired from a
<code>Symbol</code> which is in turn resolved from a <code>Frame</code>) and then writes the
de-mangled version into the given <code>writer</code>. If the symbol does not look like
a mangled symbol, it is still written to <code>writer</code>.</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>)
