Struct SerNode 

pub struct SerNode {
    pub parent: Option<u32>,
    pub children: Vec<u32>,
    pub last_child: Option<u32>,
    pub delta: Option<Delta>,
    pub cursor: (u32, u32),
    pub timestamp_unix_ms: u64,
    pub marks: MarkSnapshot,
    pub seq: u64,
}

One node of the serialized undo tree. Mirrors [UndoNode] minus the runtime-only materialization cache; ids are dense indices into SerTree::nodes.

Fields

parent: Option<u32>

Parent index, None only for the root.

children: Vec<u32>

Child indices (order preserved; > 1 ⇒ branch point).

last_child: Option<u32>

<C-r> target child index.

delta: Option<Delta>

Reversible edge delta from the parent, None only for the root.

cursor: (u32, u32)

Post-state cursor (row, col).

timestamp_unix_ms: u64

Wall-clock creation time, ms since the UNIX epoch.

marks: MarkSnapshot

Marks / jumplist / changelist snapshot.

seq: u64

Global monotonic change number.
