Struct EngineSnapshot 

pub struct EngineSnapshot { /* private fields */ }

CoW-1 (v7.34) — frozen view of the persisted committed engine state. Carries every field the snapshot() envelope serializes; Clone is O(1) on the catalog (Arc bump) and cheap typed-clones on the trailers. Decouples “capture state” from “serialize bytes” so the background-checkpoint worker can hold the snapshot and produce bytes off the engine write lock.

Implementations

impl EngineSnapshot

pub fn serialize(&self) -> Vec<u8>

Same envelope rules as Engine::snapshot(): bare catalog when every trailer is empty, full envelope otherwise.
