Module assignment

Structs

Assigner

Core assigner with configurable strategies.

AssignerBuilder

Builder for Assigner.

ScaleFactor

A validated, non-negative, finite scale factor.

VnodeChunk 🔒

A lightweight struct to represent a chunk of VNodes during assignment. This is an internal implementation detail.

Enums

BalancedBy

Defines the vnode distribution strategy for hierarchical assignment.

CapacityMode

Defines the capacity assignment strategy for containers.

VnodeChunkingStrategy

Defines the VNode chunking strategy for assignment.

Functions

assign_hierarchical

Hierarchically distributes virtual nodes to actors in two weighted stages with deterministic tie-breaking.

assign_items_weighted_with_scale_fn

Assign items to weighted containers with optional capacity scaling and deterministic tie-breaking.

compute_worker_quotas 🔒

Computes per-worker VNode quotas based on actor counts and worker weights.

stable_hash 🔒

Stable hash utility

unbounded_scale

A no-op capacity scaling function: always returns None.

vec_len_map 🔒

Helper: maps each Vec<V> to its length.

weighted_scale

A unit capacity scaling function: always returns Some(1.0).
