Enum sc_consensus_babe::PreDigest

pub enum PreDigest {
    Primary(PrimaryPreDigest),
    SecondaryPlain(SecondaryPlainPreDigest),
    SecondaryVRF(SecondaryVRFPreDigest),
}

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

impl PreDigest

pub fn authority_index(&self) -> u32

Returns the slot number of the pre digest.

pub fn slot(&self) -> Slot

Returns the slot of the pre digest.

pub fn added_weight(&self) -> u32

Returns the weight added by this digest, not the cumulative weight of the chain.

pub fn vrf_output(&self) -> Option<&VRFOutput>

Returns the VRF output, if it exists.

Trait Implementations

impl Clone for PreDigest

pub fn clone(&self) -> PreDigest

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PreDigest

pub fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Decode for PreDigest

pub fn decode<__CodecInputEdqy>(
    __codec_input_edqy: &mut __CodecInputEdqy

pub fn encoded_size(&self) -> usize

Calculates the encoded size.
