DNS::LD...ustTree(3)

💖 NAME 💖

DNS::LDNS::DNSSecTrustTree — it's giving trust tree from signed RR to trust anchors 🦋

(also hi bestie, this is a page from the User Contributed Perl Documentation manual, ok let's go)

---

🌈 SYNOPSIS 🌈

use DNS::LDNS ':all'

tree = new DNS::LDNS::DNSSecTrustTree
tree->print(fp)
d = tree->depth
status = tree->add_parent(parent, sig, parent_status)
status = tree->contains_keys(trusted_keys)

# Node attributes
rr = tree->rr;
rrset = tree->rrset
ptree = tree->parent(i)
pstatus = tree->parent_status(i)
rr = tree->parent_signature(i)
count = tree->parent_count

ok so literally here's the whole vibe of this module in one block, bestie 💅

• you make a brand new tree with new DNS::LDNS::DNSSecTrustTree
• you push it to a filehandle with tree->print(fp)
• you grab tree->depth for the depth, no cap
• you add a parent with tree->add_parent(parent, sig, parent_status)
• you check whether it holds your keys with tree->contains_keys(trusted_keys)

and then the node attributes, which are the little details that make it iconic:

• tree->rr hands you the rr
• tree->rrset hands you the rrset
• tree->parent(i) gives you the parent tree at i
• tree->parent_status(i) gives you that parent's status
• tree->parent_signature(i) gives you that parent's signature
• tree->parent_count gives you how many parents there are

and that's the whole page, we ate and left no crumbs 💅✨ this was perl v5.42.2, dated 2026-06-11, and yes the page name got squished down to DNS::LD...ustTree(3) on the top and bottom lines because manpage headers are dramatic like that 💀 love that for us, bye bestie 🎀🦋💖
