Struct Branch 

pub struct Branch {
    pub name: String,
    pub leaf: Option<NodeId>,
    pub summary: Option<BranchSummary>,
    pub created_at_ms: i64,
}

A named pointer into the tree: leaf is the node this branch currently ends at (its “current-leaf pointer”, module 21’s phrase). None only for a brand-new, still-empty tree’s implicit branch before any node exists.

Fields

name: String

The branch’s name (unique within SessionTree::branches).

leaf: Option<NodeId>

The node this branch currently points at (its leaf/current position).

summary: Option<BranchSummary>

An attached summary (module 21 “branch summaries”), set by SessionTree::summarize_branch/SessionTree::summarize_branch_with. None — the overwhelmingly common case (a branch nobody has summarized, e.g. the active one).

created_at_ms: i64

Unix-ms wall-clock time this branch was created.
