Struct EdgeStoreCheckpoint 

pub struct EdgeStoreCheckpoint {
    pub csr_version: u64,
    pub delta_edge_count: usize,
    pub delta_byte_size: usize,
    pub seq_counter: u64,
    pub tombstone_count: usize,
}

Edge store state snapshot for checkpoint/restore.

Captures the CSR version, delta buffer size, and sequence counter at checkpoint time. This lightweight checkpoint doesn’t clone the actual data - it just captures version/size info for validation.

Fields

csr_version: u64

CSR version number at checkpoint time

delta_edge_count: usize

Number of delta edges at checkpoint time

delta_byte_size: usize

Delta buffer byte size at checkpoint time

seq_counter: u64

Sequence counter value at checkpoint time

tombstone_count: usize

Number of tombstones at checkpoint time

Implementations

impl EdgeStoreCheckpoint

pub fn new( csr_version: u64, delta_edge_count: usize, delta_byte_size: usize, seq_counter: u64, tombstone_count: usize, ) -> Self

Creates a new edge store checkpoint.

pub fn has_changed( &self, current_csr_version: u64, current_delta_count: usize, current_seq: u64, ) -> bool

Returns true if the edge store state has changed since checkpoint.

Trait Implementations

impl Clone for EdgeStoreCheckpoint

fn clone(&self) -> EdgeStoreCheckpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeStoreCheckpoint

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

Formats the value using the given formatter.

impl Default for EdgeStoreCheckpoint

fn default() -> EdgeStoreCheckpoint

Returns the “default value” for a type.

impl Display for EdgeStoreCheckpoint

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

Formats the value using the given formatter.

impl PartialEq for EdgeStoreCheckpoint

fn eq(&self, other: &EdgeStoreCheckpoint) -> 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.
