[−][src]Crate sc_consensus_epochs

Generic utilities for epoch-based consensus engines.

Modules

Migration types for epoch changes.

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.

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.

Epoch	Epoch data, distinguish whether it is genesis or not.
IsDescendentOfBuilder	A builder for `is_descendent_of` functions.

Produce a descendent query object given the client.

EpochChangesFor	Type alias to produce the epoch-changes tree from a block type.
SharedEpochChanges	A shared epoch changes tree.
