Struct ReplicationManager 

pub struct ReplicationManager { /* private fields */ }

Manages replica placement for data items.

Implementations

impl ReplicationManager

pub fn new() -> Self

Create a new replication manager.

pub fn replicate(&mut self, data: &[u8], factor: u32, nodes: &[u64]) -> Vec<u64>

Replicate data to factor nodes selected from nodes.

Selection is deterministic: the first factor nodes from the slice are used. The mapping is stored internally and the selected node IDs are returned.

If nodes has fewer entries than factor, all provided nodes are used.

pub fn replica_nodes(&self, data: &[u8]) -> Option<&[u64]>

Return the nodes holding replicas for the given data.

pub fn record_count(&self) -> usize

Total number of tracked replication records.

Trait Implementations

impl Debug for ReplicationManager

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

Formats the value using the given formatter.

impl Default for ReplicationManager

fn default() -> ReplicationManager

Returns the “default value” for a type.
