Enum sp_consensus_babe::digests::PreDigest [−][src]
pub enum PreDigest {
Primary(PrimaryPreDigest),
SecondaryPlain(SecondaryPlainPreDigest),
SecondaryVRF(SecondaryVRFPreDigest),
}Expand description
A BABE pre-runtime digest. This contains all data required to validate a block and for the BABE runtime module. Slots can be assigned to a primary (VRF based) and to a secondary (slot number based).
Variants
Primary(PrimaryPreDigest)A primary VRF-based slot assignment.
SecondaryPlain(SecondaryPlainPreDigest)A secondary deterministic slot assignment.
SecondaryVRF(SecondaryVRFPreDigest)A secondary deterministic slot assignment with VRF outputs.
Implementations
Returns the slot number of the pre digest.
Returns the weight added by this digest, not the cumulative weight of the chain.
Returns the VRF output, if it exists.
