Module save 

Save / Load System

Provides serialization, world snapshots, file-level save formats, save slot management, and checkpoint-based respawn for the Proof Engine game loop.

Modules

Module	Purpose
serializer	SerializedValue enum (JSON-like), Serialize/Deserialize traits, built-in impls
snapshot	WorldSnapshot, EntitySnapshot, SnapshotDiff
format	SaveFile, SaveHeader, SaveManager, slot management
checkpoint	Checkpoint, CheckpointManager, RespawnSystem

Quick save example

use proof_engine::save::{
    snapshot::WorldSnapshot,
    format::{SaveFile, SaveManager},
};

let mut snapshot = WorldSnapshot::new();
let mut save_manager = SaveManager::new("saves/");
save_manager.save_to_slot(0, snapshot, Default::default()).unwrap();
let file = save_manager.load_slot(0).unwrap();

Modules

checkpoint

Checkpoint system — spatial save points and respawn management.

cloud

Cloud save synchronisation: upload/download queuing, conflict resolution, offline buffering, encryption, and rotating local backups.

compression

Compression algorithms for save data: RLE, LZ4-style, Huffman, and delta encoding.

format

Save file format, slot management, and the SaveManager.

migrations

Schema migration system for save data.

profile

User profiles, play statistics, local leaderboards, unlockables, and the prestige system.

serializer

Custom serialization layer for the save system.

snapshot

World snapshots — serializable representations of the entire game state.
