Struct crdts::orswot::Orswot

pub struct Orswot<Member: Ord + Clone + Serialize + DeserializeOwned, Actor: Ord + Clone + Serialize + DeserializeOwned> { /* fields omitted */ }

Orswot is an add-biased or-set without tombstones ported from the riak_dt CRDT library.

Methods

impl<Member: Ord + Clone + Serialize + DeserializeOwned, Actor: Ord + Clone + Serialize + DeserializeOwned> Orswot<Member, Actor>

fn new() -> Orswot<Member, Actor>

Returns a new Orswot instance.

fn add(&mut self, member: Member, actor: Actor)

Add a single element.

Safety

add should never be passed identical actor arguments for different replicas. This will result in data loss:

use crdts::Orswot;
let (mut a, mut b) = (Orswot::new(), Orswot::new());
a.add(1, 1);
b.add(2, 1);
a.merge(b);
assert!(a.value().is_empty());

fn add_all(&mut self, members: Vec<Member>, actor: Actor)

Add several members.

unsafe fn remove(&mut self, member: Member) -> Option<VClock<Actor>>

Remove a member without providing a witnessing context. Returns an existing context VClock if it was present.

fn remove_with_context(&mut self, member: Member, context: &VClock<Actor>)

Remove a member using a witnessing context.

unsafe fn remove_all(
    &mut self,
    members: Vec<Member>
) -> Vec<Option<VClock<Actor>>>

Remove multiple members, without providing a witnessing context.

fn remove_all_with_context(
    &mut self,
    members: Vec<Member>,
    context: &VClock<Actor>
)

Remove multiple members with a witnessing context.

fn value(&self) -> Vec<Member>

Retrieve the current members.

fn merge(&mut self, other: Orswot<Member, Actor>)

Merge combines another Orswot with this one.

fn precondition_context(&self) -> VClock<Actor>

Returns the current VClock associated with this Orswot.
