Crate sc_consensus_epochs

Generic utilities for epoch-based consensus engines.

Modules

migration

Migration types for epoch changes.

Structs

EpochChanges

Tree of all epoch changes across all seen forks. Data stored in tree is the hash and block number of the block signaling the epoch change, and the epoch that was signalled at that block.

EpochHeader

Header of epoch data, consisting of start and end slot.

EpochIdentifier

Epoch identifier.

HeaderBackendDescendentBuilder

Wrapper to get around unconstrained type errors when implementing IsDescendentOfBuilder for header backends.

IncrementedEpoch

A fresh, incremented epoch to import into the underlying fork-tree.

Enums

EpochIdentifierPosition

Position of the epoch identifier.

PersistedEpoch

Persisted epoch stored in EpochChanges.

PersistedEpochHeader

Persisted epoch header stored in ForkTree.

ViableEpoch

The viable epoch under which a block can be verified.

ViableEpochDescriptor

Descriptor for a viable epoch.

Traits

Epoch

Epoch data, distinguish whether it is genesis or not.

IsDescendentOfBuilder

A builder for is_descendent_of functions.

Functions

descendent_query

Produce a descendent query object given the client.

Type Aliases

EpochChangesFor

Type alias to produce the epoch-changes tree from a block type.

SharedEpochChanges

A shared epoch changes tree.
