Struct SaveState 

pub struct SaveState { /* private fields */ }

A captured snapshot of a System, ready to be encoded to bytes or restored back into a running system.

Implementations

impl SaveState

pub fn capture(system: &System, rom_tag: u64) -> Self

Captures system as a save-state tagged with rom_tag (an opaque caller-supplied ROM identity, e.g. a hash of the loaded ROM image).

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

Encodes this save-state to its binary wire format.

pub fn decode(bytes: &[u8]) -> Result<Self, SaveStateError>

Decodes a save-state from its binary wire format, without checking it against any particular ROM yet (see Self::restore for that).

pub fn restore(bytes: &[u8], rom_tag: u64) -> Result<System, SaveStateError>

Decodes and validates a save-state against rom_tag, returning the System it captured. Fails with SaveStateError::RomMismatch if the save-state was captured for a different ROM.

pub fn into_system(self) -> System

The System this save-state captured, without any ROM-tag check — for callers (like the rewind ring) that already know the ROM can’t have changed since capture.
