Struct XorDelta 

pub struct XorDelta {
    pub prev_hash: [u8; 32],
    pub new_hash: [u8; 32],
    pub patch: Vec<u8>,
    pub new_len: usize,
}

XOR delta for state synchronization

Fields

prev_hash: [u8; 32]

Hash of previous state

new_hash: [u8; 32]

Hash of new state

patch: Vec<u8>

Run-length encoded XOR patch

new_len: usize

Original new state length (needed for applying delta)

Implementations

impl XorDelta

pub fn compute(prev: &[u8], new: &[u8]) -> Self

Compute delta between two states

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

Apply delta to state Returns the new state if successful

pub fn patch_size(&self) -> usize

Get the size of the compressed patch

pub fn is_sparse(&self, full_state_size: usize) -> bool

Check if this delta represents a sparse change (patch is smaller than the full state)

pub fn verify_prev_hash(&self, state: &[u8]) -> bool

Verify the delta can be applied to a state

Trait Implementations

impl Clone for XorDelta

fn clone(&self) -> XorDelta

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for XorDelta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for XorDelta

impl PartialEq for XorDelta

fn eq(&self, other: &XorDelta) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
