Module selection

Backend selection interfaces and algorithms

Modules

• algorithms
  Implementation of algorithms for weighted selection
• consistent
  Consistent Hashing
• weighted
  Weighted Selection

Structs

• UniqueIterator
  An iterator which wraps another iterator and yields unique items. It optionally takes a max number of iterations if the wrapped iterator never returns.

Traits

• BackendIter
  An iterator to find the suitable backend
• BackendSelection
  BackendSelection is the interface to implement backend selection mechanisms.
• SelectionAlgorithm
  SelectionAlgorithm is the interface to implement selection algorithms.

Type Aliases

• Consistent
  Consistent Ketama hashing on weighted backends
• FNVHash
  FNV hashing on weighted backends
• Random
  Random selection on weighted backends
• RoundRobin
  Round robin selection on weighted backends
