Struct ron_crdt::LWW

pub struct LWW;

An LWW is an associated map from UUIDs to Atoms. Conflicting writes are merge by using the Op event timestamp. The last writes wins.

Implementations

impl LWW

pub fn set<'a>(state: &Frame<'a>, key: UUID, value: Atom) -> Option<Frame<'a>>

Sets key to value in LWW state. Returns the update Frame without modifing the state.

Trait Implementations

impl CRDT for LWW

type T = HashMap<UUID, Atom, RandomState>

Rust type this CRDT can be mapped to.

fn new<'a>(obj: UUID) -> Frame<'a>

Returns the state Frame of a new, empty CRDT instance with UUID obj.

fn reduce<'a>(state: Frame<'a>, updates: Vec<Frame<'a>>) -> Option<Frame<'a>>

Reduce state Frame state and update Frames updates to a new state Frame.

fn map<'a>(state: Frame<'a>) -> Option<Self::T>

Maps the state Frame state to a Rust type.
