Struct PartitionRouter 

pub struct PartitionRouter { /* private fields */ }

Routes execution operations to the correct partition.

In a Valkey Cluster deployment, the ferriskey client handles slot-level routing transparently — all keys for a partition share the same {p:N} hash tag, so they land on the same shard. The router’s job is partition computation and key context construction, not connection selection.

Implementations

impl PartitionRouter

pub fn new(config: PartitionConfig) -> Self

pub fn partition_for(&self, eid: &ExecutionId) -> Partition

Resolve an execution ID to its partition.

pub fn exec_keys(&self, eid: &ExecutionId) -> ExecKeyContext

Build an ExecKeyContext for the given execution.

pub fn index_keys(&self, partition_index: u16) -> IndexKeys

Build IndexKeys for a given partition index.

pub fn config(&self) -> &PartitionConfig

The partition config.

pub fn num_flow_partitions(&self) -> u16

Total number of flow partitions.

Post-RFC-011: exec keys co-locate with their parent flow’s partition under hash-tag routing, so this count governs exec routing too. There is no separate num_execution_partitions.
