Enum ConsistencyLevel 

pub enum ConsistencyLevel {
    Strong,
    Eventual,
    Quorum {
        read_quorum: usize,
        write_quorum: usize,
    },
    One,
}

Consistency level for read and write operations

Variants

Strong

Strong consistency - all replicas must agree

Eventual

Eventual consistency - accept stale reads, async replication

Quorum

Quorum-based consistency - R + W > N for linearizability

Fields

read_quorum: usize

write_quorum: usize

One

One - only one replica needs to respond (fastest, least consistent)

Trait Implementations

impl Clone for ConsistencyLevel

fn clone(&self) -> ConsistencyLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConsistencyLevel

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

Formats the value using the given formatter.

impl Default for ConsistencyLevel

fn default() -> ConsistencyLevel

Returns the “default value” for a type.

impl PartialEq for ConsistencyLevel

fn eq(&self, other: &ConsistencyLevel) -> 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 Copy for ConsistencyLevel

impl Eq for ConsistencyLevel

impl StructuralPartialEq for ConsistencyLevel
