Struct CrdtMetadata 

pub struct CrdtMetadata {
    pub clock: HashMap<String, u64>,
    pub origin: String,
    pub seq: u64,
}

CRDT metadata for a content block.

Each content block can carry CRDT metadata for tracking distributed state. This enables conflict-free merging of concurrent edits.

Fields

clock: HashMap<String, u64>

Vector clock mapping site IDs to logical timestamps.

origin: String

Site ID where this version originated.

seq: u64

Sequence number within the origin site.

Implementations

impl CrdtMetadata

pub fn new(origin: impl Into<String>, seq: u64) -> Self

Create new CRDT metadata.

pub fn increment(&mut self, site_id: &str)

Increment the sequence number for a site.

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

Merge with another CRDT metadata (takes maximum of each clock entry).

pub fn happened_before(&self, other: &Self) -> bool

Check if this metadata happened before another (causally).

Trait Implementations

impl Clone for CrdtMetadata

fn clone(&self) -> CrdtMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrdtMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrdtMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CrdtMetadata

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

impl Serialize for CrdtMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
