Struct PackListNode 

pub struct PackListNode {
    pub prev: Option<Hash>,
    pub packs: Vec<Hash>,
}

A single node in a branch’s packlist chain.

The push path appends one node per push: prev points at the previous node (the current packmap value before this push), and packs holds the pack(s) this push added. The full ordered pack set for a branch is the chain walked oldest-first — see remote_dispatch::fetch_pack_chain.

Chaining keeps each push O(1) on the wire (read a 32-byte pointer, write a ~64-byte node) instead of re-uploading the whole history’s list.

A node’s prev is reset to None (rather than linked to the prior head) when a push re-baselines (#406) — proactively bounding chain depth, or reactively escaping a broken chain. Either way the packs the superseded chain referenced become unreachable from the new head node: they are not deleted here (this module only ever writes new nodes/packs, never deletes), so they linger as orphaned storage on the remote until a server-side sweep reclaims them (tracked as makechain#849). A stale pack lingering harmlessly is safe; nothing on the fetch side ever resolves it once no live chain points to it.

Fields

prev: Option<Hash>

Previous node’s key, or None for the first node of a branch.

packs: Vec<Hash>

Pack keys added by this node, in apply order.
