Struct Set 

pub struct Set<T: Eq + Hash + Clone> { /* private fields */ }

OR-Set CRDT. See the module docs for semantics.

Implementations

impl<T: Eq + Hash + Clone> Set<T>

pub fn new(replica: ReplicaId) -> Self

Create an empty set.

pub fn new_random() -> Self

Create a new instance with a random ReplicaId from OS entropy. See crate::new_replica_id.

pub fn replica_id(&self) -> ReplicaId

This replica’s id.

pub fn len(&self) -> usize

Number of distinct values currently in the set.

pub fn is_empty(&self) -> bool

Is the set empty?

pub fn contains(&self, value: &T) -> bool

Does the set contain value?

pub fn iter(&self) -> impl Iterator<Item = &T> + '_

Iterate over values currently in the set.

pub fn add(&mut self, value: T) -> SetOp<T>

Add value. If it’s already present, an additional tag is created; removing it then requires a remove op that observes both tags (which always happens when removes carry the tag list at remove-time).

pub fn remove(&mut self, value: &T) -> Option<SetOp<T>>

Remove value. No-op (returns None) if the value is not present.

pub fn apply(&mut self, op: SetOp<T>) -> Result<(), Error>

Apply a remote op. Idempotent.

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

Merge all of other’s state into self.

pub fn ops(&self) -> &[SetOp<T>]

All ops in this set’s log.

pub fn ops_since<'a>( &'a self, since: &'a VersionVector, ) -> impl Iterator<Item = &'a SetOp<T>> + 'a

Iterate over ops not yet seen by since.

pub fn version(&self) -> &VersionVector

This replica’s current version vector.

Trait Implementations

impl<T: Clone + Eq + Hash + Clone> Clone for Set<T>

fn clone(&self) -> Set<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Eq + Hash + Clone> Debug for Set<T>

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

Formats the value using the given formatter.

impl<T: Eq + Hash + Clone> Default for Set<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Set<T>

where T: Eq + Hash + Clone + Deserialize<'de>,

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(de: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl<T> Serialize for Set<T>

where T: Eq + Hash + Clone + Serialize,

Available on crate feature serde only.

fn serialize<S: Serializer>(&self, ser: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
