Enum sp_consensus_babe::digests::PreDigest
source · 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§
source§impl PreDigest
impl PreDigest
Returns the slot number of the pre digest.
sourcepub fn is_primary(&self) -> bool
pub fn is_primary(&self) -> bool
Returns true if this pre-digest is for a primary slot assignment.
sourcepub fn added_weight(&self) -> BabeBlockWeight
pub fn added_weight(&self) -> BabeBlockWeight
Returns the weight added by this digest, not the cumulative weight of the chain.
