Module contracts 

User-facing Contract traits — canonical home is bb-runtime::contracts. This module re-exports the traits for authoring ergonomics so bb_dsl::contracts::Index etc. keep resolving.

Modules

aggregator

Re-export of the bb::Aggregator Contract trait for federated aggregators.

backend

Re-export of the bb::Backend Contract trait for tensor compute backends.

backend_default_walk

Re-export of the shared default-walker bridges between Backend’s per-op methods and whole-graph execute.

codec

Re-export of the bb::Codec Contract trait for bidirectional storage-type codecs.

data_source

Re-export of the bb::DataSource Contract trait for data loaders.

index

Re-export of the bb::Index Contract trait for vector indexes.

model

Re-export of the bb::Model Contract trait for ML models.

peer_selector

Re-export of the bb::PeerSelector Contract trait for peer-selection protocols.

Enums

SelectParams

Parameters describing what peer set to select. Different concrete selectors handle the variants they support and return an error variant for the ones they don’t (e.g. GlobalRegistry supports Random + All; DhtView supports NearKey).

Traits

Aggregator

User-facing Contract trait for a federated/decentralized aggregator. The derive bridges these methods to the engine’s crate::roles::AggregatorRuntime trait.

Backend

User-facing Contract trait for a tensor compute backend.

Codec

User-facing Contract trait for a typed in/out storage codec.

DataSource

User-facing Contract trait for a data source / data loader.

Index

User-facing Contract trait for a vector index.

Model

User-facing Contract trait for an ML model.

PeerSelector

User-facing Contract trait for a peer-selection protocol.
