Struct VectorClock 

pub struct VectorClock { /* private fields */ }

벡터 클록

node_id → logical_clock 의 맵으로 구성됩니다.

Implementations

impl VectorClock

pub fn new() -> Self

새 빈 벡터 클록 생성

pub fn get(&self, node_id: u32) -> u64

특정 노드의 논리 클록 값 조회

pub fn tick(&mut self, node_id: u32)

특정 노드의 클록을 1 증가 (이벤트 발생 시 호출)

pub fn merge_and_tick(&mut self, other: &VectorClock, self_node_id: u32)

메시지 수신 시 병합: self[node] = max(self[node], other[node]) + tick

pub fn merge(&mut self, other: &VectorClock)

단순 병합 (tick 없이)

pub fn compare(&self, other: &VectorClock) -> VectorClockOrder

두 벡터 클록을 비교하여 인과관계 판단

pub fn happens_before(&self, other: &VectorClock) -> bool

self가 other보다 먼저 발생했는지 여부

pub fn is_concurrent(&self, other: &VectorClock) -> bool

두 클록이 동시 발생(충돌)인지 여부

Trait Implementations

impl Clone for VectorClock

fn clone(&self) -> VectorClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorClock

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

Formats the value using the given formatter.

impl Default for VectorClock

fn default() -> VectorClock

Returns the “default value” for a type.

impl PartialEq for VectorClock

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