Struct CheckpointDiff 

pub struct CheckpointDiff {
    pub base_step: u64,
    pub target_step: u64,
    pub edits: Vec<(usize, u8, u8)>,
}

Binary difference between two checkpoints.

Stores edit operations as a sequence of byte-level patches that transform base into target. Apply with CheckpointDiff::apply.

Fields

base_step: u64

Step number of the base checkpoint.

target_step: u64

Step number of the target checkpoint.

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

Sequence of (offset, old_byte, new_byte) edits.

Implementations

impl CheckpointDiff

pub fn compute( base_step: u64, base: &[u8], target_step: u64, target: &[u8], ) -> Self

Compute the diff between base and target state byte slices.

The diff records every position where base and target differ.

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

Apply the diff to base_state to reconstruct target_state.

Returns an error if any edit offset falls out of bounds.

pub fn diff_size(&self) -> usize

Number of bytes that differ between base and target.

pub fn change_ratio(&self, base_len: usize) -> f64

Fraction of bytes that changed (relative to the base state length).

Trait Implementations

impl Clone for CheckpointDiff

fn clone(&self) -> CheckpointDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointDiff

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

Formats the value using the given formatter.
