Struct LWWField 

pub struct LWWField {
    pub value: Value,
    pub timestamp: Timestamp,
}

A field value with LWW metadata

Fields

value: Value

The actual field value (JSON-like)

timestamp: Timestamp

Timestamp for conflict resolution

Implementations

impl LWWField

pub fn new(value: JsonValue, timestamp: Timestamp) -> Self

Create a new LWW field with a value and timestamp

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

Merge two LWW fields using Last-Write-Wins semantics

This follows the TLA+ verified algorithm:

• If remote is newer (higher timestamp), use remote
• If local is newer, keep local
• If equal timestamps, use deterministic tie-breaking via client_id

pub fn is_newer_than(&self, other: &LWWField) -> bool

Check if this field is newer than another

Trait Implementations

impl Clone for LWWField

fn clone(&self) -> LWWField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LWWField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LWWField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LWWField

fn eq(&self, other: &LWWField) -> 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 LWWField

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
