XF 2.0 Double curly brackets in templates?

[Marcel]

For example :

<a href="{{ link('forums', $forum, {'prefix_id': $thread.prefix_id}) }}" class="labelLink" rel="nofollow">{{ prefix('thread', $thread, 'html', '') }}</a>

I can see there is a link(), prefix(), and a couple of others in the XF2 templates.
I can see theyre pulling variables and building a link / text.
What others are available, and where in the code structure can I find them (and hopefully figure out how to use them myself)?

I think may have found it.
Is it in src\XF\Template\Templater.php

fnLink
fnPrefix
etc?

This should help you with template syntax: https://xenforo.com/xf2-docs/dev/template-syntax/

Yep, those are template functions in Templater class.
