Till Kamppeter<p>Hi, anybody here is experienced in Rust (perhaps even also in creating bindings for a C library/API) and would like to mentor a GSoC contributor for OpenPrinting? The contributor will work a total of 3 months full-time (or 350 hours) in the time from May to November this year on the project and they will get a stipend from Google.</p><p>Only additional requirements are a minimum age of 18 and not to want to participate as GSoC contributor this year or in any later year.</p><p><a href="https://ubuntu.social/tags/OpenPrinting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenPrinting</span></a> <a href="https://ubuntu.social/tags/Rust" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Rust</span></a> <a href="https://ubuntu.social/tags/CUPS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CUPS</span></a></p>
