Module prio::idpf

Available on crate features crypto-dependencies and experimental only.

This module implements the incremental distributed point function (IDPF) described in [draft-irtf-cfrg-vdaf-08].

Modules

• test_utilstest-util
  Utilities for testing IDPFs.

Structs

• HashMapCache
  A simple IdpfCache implementation that caches intermediate results in an in-memory hash map, with no eviction.
• Idpf
  This defines a family of IDPFs (incremental distributed point functions) with certain types of values at inner tree nodes and at leaf tree nodes.
• IdpfInput
  An index used as the input to an IDPF evaluation.
• IdpfPublicShare
  An IDPF public share. This contains the list of correction words used by all parties when evaluating the IDPF.
• NoCache
  A no-op IdpfCache implementation that always reports a cache miss.
• RingBufferCache
  A simple IdpfCache implementation that caches intermediate results in memory, with first-in-first-out eviction, and lookups via linear probing.

Enums

• IdpfError
  IDPF-related errors.
• IdpfOutputShare
  An output from evaluation of an IDPF at some level and index.

Traits

• IdpfCache
  An interface that provides memoization of IDPF computations.
• IdpfValue
  Trait for values to be programmed into an IDPF.
