[<code>MemFlags::new().read_write()</code>]).</p>
<p><code>flags</code>: A bit-field that is used to specify allocation and usage
information about the sub-buffer memory object being created and is
described in the table below. If the <code>MEM_READ_WRITE</code>, <code>MEM_READ_ONLY</code>
or <code>MEM_WRITE_ONLY</code> values are not specified in flags, they are
inherited from the corresponding memory access qualifers associated
with buffer. The <code>MEM_USE_HOST_PTR</code>, <code>MEM_ALLOC_HOST_PTR</code> and
<code>MEM_COPY_HOST_PTR</code> values cannot be specified in flags but are
inherited from the corresponding memory access qualifiers associated
with buffer. If <code>MEM_COPY_HOST_PTR</code> is specified in the memory access
qualifier values associated with buffer it does not imply any
additional copies when the sub-buffer is created from buffer. If the
<code>MEM_HOST_WRITE_ONLY</code>, <code>MEM_HOST_READ_ONLY</code> or <code>MEM_HOST_NO_ACCESS</code>
values are not specified in flags, they are inherited from the
corresponding memory access qualifiers associated with buffer.</p>

                <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>)
                </p>
