Crate sp_consensus

Common utilities for building and using consensus engines in substrate.

Much of this crate is unstable and thus the API is likely to undergo change. Implementors of traits should not rely on the interfaces to remain the same.

Re-exports

pub use self::error::Error;

Modules

block_validation

Block announcement validation.

error

Error types for consensus modules.

Structs

DisableProofRecording

Express that proof recording is disabled.

EnableProofRecording

Express that proof recording is enabled.

InherentData

Inherent data to include in a block.

NoNetwork

A synchronization oracle for when there is no network.

NoProofRecorded

Error that is returned when ProofRecording requested to record a proof, but no proof was recorded.

Proposal

A proposal that is created by a Proposer.

Enums

BlockOrigin

Block data origin.

BlockStatus

Block status.

Traits

Environment

Environment for a Consensus instance.

ProofRecording

A trait to express the state of proof recording on type system level.

Proposer

Logic for a proposer.

SelectChain

The SelectChain trait defines the strategy upon which the head is chosen if multiple forks are present for an opaque definition of “best” in the specific chain build.

StateBackend

A state backend is used to read state data and can have changes committed to it.

SyncOracle

An oracle for when major synchronization work is being undertaken.
