Struct ron_crdt::Set

pub struct Set;

2-Phase sets are sets of atoms.

Each element is associated with the timestamp of the Op that inserted it. Removing elements is done my inserting a tombstone. Thus, deletions override insertions.

Methods

impl Set

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

Inserts value into the Set state. Returns the update Frame without modifying the Set.

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

Removes value from the Set state by inserting a tombstone for all insertions of value. Returns the update Frame without modifying the Set.

Trait Implementations

impl CRDT for Set

type T = HashSet<Atom>

Rust type this CRDT can be mapped to.

Important traits for Frame<'a>

impl<'a> Iterator for Frame<'a> type Item = Op;

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.
