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.

Modules

block_import	Block import helpers.
block_validation	Block announcement validation.
error	Error types in Consensus
evaluation	Block evaluation and evaluation errors.
import_queue	Import Queue primitive: something which can verify and import blocks.
offline_tracker	Tracks offline validators.

Structs

AlwaysCanAuthor	Returns always true for can_author_with. This is useful for tests.
CanAuthorWithNativeVersion	Checks if the node can author blocks by using NativeVersion::can_author_with.
InherentData	Inherent data to include in a block.
NeverCanAuthor	Never can author.
NoNetwork	A synchronization oracle for when there is no network.
Proposal	A proposal that is created by a Proposer.

Enums

BlockStatus	Block status.
RecordProof	Used as parameter to Proposer to tell the requirement on recording a proof.

Traits

CanAuthorWith	Checks if the current active native block authoring implementation can author with the runtime at the given block.
Environment	Environment for a Consensus instance.
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.
SlotData	A type from which a slot duration can be obtained.
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.
