Struct SerTree 

pub struct SerTree {
    pub base: Option<String>,
    pub nodes: Vec<SerNode>,
    pub root: u32,
    pub current: u32,
    pub next_seq: u64,
}

Serializable projection of an [UndoTree] for the undofile and the swap undo section. Postcard-encoded (non-self-describing, so a schema/version drift surfaces as a parse Err that the reader discards). See [UndoTree::to_serializable] / [UndoTree::from_serializable].

Fields

base: Option<String>

Root base text (the anchor the delta chain replays from). Always Some on write; from_serializable rejects None — a tree without an anchor is structurally invalid outside the swap context. The swap writer drops it for single-node trees (the body IS the base) and the swap reader re-substitutes the body text before the tree is rebuilt.

nodes: Vec<SerNode>

Dense node arena (no holes).

root: u32

Root index into nodes.

current: u32

Current (live) index into nodes.

next_seq: u64

Next seq to assign.
