Struct VersionVector 

pub struct VersionVector { /* private fields */ }

Version vector for causal ordering (not total ordering)

Implementations

impl VersionVector

pub fn new() -> Self

pub fn get(&self, node: NodeId) -> u64

Get the clock value for a node

pub fn increment(&mut self, node: NodeId)

Increment the clock for a node

pub fn set(&mut self, node: NodeId, value: u64)

Set the clock for a node

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

pub fn concurrent(&self, other: &VersionVector) -> bool

Check if two version vectors are concurrent (neither happens-before)

pub fn merge(&self, other: &VersionVector) -> VersionVector

Merge two version vectors (element-wise max)

pub fn to_compact(&self) -> Vec<(NodeId, u64)>

Compact representation for wire format

pub fn from_compact(entries: Vec<(NodeId, u64)>) -> Self

Restore from compact representation

Trait Implementations

impl Clone for VersionVector

fn clone(&self) -> VersionVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VersionVector

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

Formats the value using the given formatter.

impl Default for VersionVector

fn default() -> VersionVector

Returns the “default value” for a type.

impl PartialEq for VersionVector

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