Struct StateDelta 

pub struct StateDelta {
    pub base_frame: u64,
    pub target_frame: u64,
    pub changes: Vec<(usize, Vec<u8>)>,
    pub checksum: u64,
}

Delta-encoded state snapshot for efficient storage

Per Lavoie [9]: Delta encoding achieves 94% overhead reduction compared to full snapshots.

Fields

base_frame: u64

Base frame this delta applies to

target_frame: u64

Target frame after applying delta

changes: Vec<(usize, Vec<u8>)>

Changed memory regions (offset, data)

checksum: u64

Checksum of resulting state

Implementations

impl StateDelta

pub fn empty(frame: u64) -> Self

Create an empty delta

pub fn compute( base: &[u8], current: &[u8], base_frame: u64, target_frame: u64, ) -> Self

Compute delta between two memory snapshots

pub fn apply(&self, base: &[u8]) -> Vec<u8>

Apply delta to base snapshot

pub fn verify(&self, data: &[u8]) -> bool

Verify the checksum matches
