Struct EnableWinsFlag 

pub struct EnableWinsFlag<K: Ord> { /* private fields */ }

Enable-wins boolean flag.

This is a flat tested-not-proven type. It mirrors an OR-Set over a unit element: enable adds a unique token, disable tombstones observed tokens, and concurrent unobserved enables remain live.

Implementations

impl<K: Ord> EnableWinsFlag<K>

pub fn new() -> Self

pub fn enable(&mut self, token: K)

pub fn disable<I>(&mut self, tokens: I)

where I: IntoIterator<Item = K>,

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

where K: Clone,

pub fn enables(&self) -> &BTreeSet<K>

pub fn tombstones(&self) -> &BTreeSet<K>

impl<K: Ord + Clone> EnableWinsFlag<K>

pub fn observed_tokens(&self) -> BTreeSet<K>

pub fn value(&self) -> bool

Trait Implementations

impl<K: Clone + Ord> Clone for EnableWinsFlag<K>

fn clone(&self) -> EnableWinsFlag<K>

Returns a duplicate of the value. Read more

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

Performs copy-assignment from source. Read more

impl<K: Ord + Clone> Crdt for EnableWinsFlag<K>

fn validate_record( &self, id: RecordId, _delta: &Self::Delta, ) -> Result<(), WireError>

Accepts every positive-sequence record, by the same argument as crate::OrSet: an enable joins the enable set even when its token is tombstoned, a disable tombstones the tokens it names whether observed or not, and a disable naming no tokens is the lattice bottom. Every decodable record applies on a fresh flag.

type Delta = EnableWinsFlagDelta<K>

fn apply_delta(&mut self, delta: Self::Delta)

fn replica_count(&self) -> Option<usize>

Fixed replica domain, or None for CRDTs without a fixed arity.

impl<K: Debug + Ord> Debug for EnableWinsFlag<K>

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

Formats the value using the given formatter. Read more

impl<K: Ord> Default for EnableWinsFlag<K>

fn default() -> Self

Returns the “default value” for a type. Read more

impl<K: Ord + Clone> Mergeable for EnableWinsFlag<K>

fn merge(&mut self, other: &Self) -> Result<(), MergeError>

Join compatible states, returning an error if their replica domains differ.

impl<K: PartialEq + Ord> PartialEq for EnableWinsFlag<K>

fn eq(&self, other: &EnableWinsFlag<K>) -> 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 WireDecode for EnableWinsFlag<u64>

fn decode_wire(cursor: &mut WireCursor<'_>) -> Result<Self, WireError>

fn decode_wire_with_collection_limits( cursor: &mut WireCursor<'_>, limits: CollectionLimits, ) -> Result<Self, WireError>

Decode a nested payload with a collection budget. Other payload types retain their ordinary decoder unless they implement this method.

fn decode_wire_with_limits( cursor: &mut WireCursor<'_>, collections: CollectionLimits, _max_records: Option<usize>, ) -> Result<Self, WireError>

Decode a payload nested in an EventLog with its record budget.

fn from_wire_bytes_with_collection_limits( bytes: &[u8], limits: CollectionLimits, ) -> Result<Self, WireError>

Decode a complete wire value with an explicit collection ceiling.

fn from_wire_bytes(bytes: &[u8]) -> Result<Self, WireError>

impl WireEncode for EnableWinsFlag<u64>

fn encode_wire(&self, out: &mut Vec<u8>) -> Result<(), WireError>

fn to_wire_bytes(&self) -> Result<Vec<u8>, WireError>

impl WireSchema for EnableWinsFlag<u64>

const REQUIRES_ARITY: bool = false

fn wire_schema() -> Cow<'static, [u8]>

Borrow fixed identities; return owned bytes for composed schemas.
