DistributedCacheClient

Struct DistributedCacheClient 

Source
pub struct DistributedCacheClient {
    pub local_node: NodeId,
    pub ring: ConsistentHash,
}
Expand description

Per-node client that wraps a ConsistentHash ring and provides key routing from the perspective of local_node.

Fields§

§local_node: NodeId

The node this client represents.

§ring: ConsistentHash

Shared ring (each client holds its own copy for isolation in this in-process model; in a real system this would be a shared reference).

Implementations§

Source§

impl DistributedCacheClient

Source

pub fn new(local_node: NodeId, ring: ConsistentHash) -> Self

Create a new client for local_node with the given ring.

Source

pub fn route_key(&self, key: &[u8]) -> NodeId

Determine which node should own key.

Returns local_node when the ring is empty (degenerate single-node mode).

Source

pub fn is_local_key(&self, key: &[u8]) -> bool

Return true if key maps to local_node (i.e. this node is the primary owner).
