<div dir="ltr">hi Bill, yeah, that's what I'll do. It's not webassembly specific, more web specific. GUIDs are used in web dev when you want a unique DB key without having to go to the DB first to generate it. The entropy length is chosen so that a collision should not happen within a billion years or something ridiculous like that. Rolling my own was pretty straightforward, and this isn't going in avionics! :-)<div><br></div><div>thanks</div><div>iain</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sat, Jun 21, 2025 at 2:40 PM <<a href="mailto:bil@ccrma.stanford.edu">bil@ccrma.stanford.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I see online that a guid is a 128-bit text string,<br>

something crucial. How are these used in webassembly?<br>
