Enum WriteConsistency 

#[non_exhaustive]
pub enum WriteConsistency {
    Local,
    All {
        timeout: Duration,
    },
    Majority {
        timeout: Duration,
    },
    From {
        n: usize,
        timeout: Duration,
    },
}

Phase 8.D — typed consistency levels with timeouts. The current in-process Replicator runs every operation as Local (single-node store); cross-node All/Majority/From(n) semantics activate once Phase 6 gossip lands.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl WriteConsistency

pub fn required_acks(self, cluster_size: usize) -> usize

Number of nodes that must acknowledge before the write is considered complete (1 for Local).

pub fn timeout(self) -> Option<Duration>

Trait Implementations

impl Clone for WriteConsistency

fn clone(&self) -> WriteConsistency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteConsistency

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

Formats the value using the given formatter.

impl PartialEq for WriteConsistency

fn eq(&self, other: &WriteConsistency) -> 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.
