BABE epoch information

Fields

epoch_index: u64

The epoch index.

start_slot: Slot

The starting slot of the epoch.

duration: u64

The duration of this epoch.

authorities: Vec<(AuthorityId, BabeAuthorityWeight)>

The authorities and their weights.

randomness: [u8; 32]

Randomness for this epoch.

config: BabeEpochConfiguration

Configuration of the epoch.

Implementations

impl Epoch

pub fn genesis(genesis_config: &BabeGenesisConfiguration, slot: Slot) -> Epoch

Create the genesis epoch (epoch #0). This is defined to start at the slot of the first block, so that has to be provided.

Trait Implementations

impl Clone for Epoch

fn clone(&self) -> Epoch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Epoch

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

Formats the value using the given formatter.

impl Decode for Epoch

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

pub fn skip<I>(input: &mut I) -> Result<(), Error> where
    I: Input, 

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for Epoch

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

pub fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

pub fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

pub fn using_encoded<R, F>(&self, f: F) -> R where
    F: FnOnce(&[u8]) -> R, 

Convert self to a slice and then invoke the given closure with it.

pub fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Epoch for Epoch

type NextEpochDescriptor = (NextEpochDescriptor, BabeEpochConfiguration)

Descriptor for the next epoch.

type Slot = Slot

Type of the slot number.

fn increment(
    &self,
    (descriptor, config): (NextEpochDescriptor, BabeEpochConfiguration)
) -> Epoch

Increment the epoch data, using the next epoch descriptor.

fn start_slot(&self) -> Slot

The starting slot of the epoch.

fn end_slot(&self) -> Slot

Produce the “end slot” of the epoch. This is NOT inclusive to the epoch, i.e. the slots covered by the epoch are self.start_slot() .. self.end_slot().

impl PartialEq<Epoch> for Epoch

fn eq(&self, other: &Epoch) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Epoch) -> bool

This method tests for !=.
