Struct sp_consensus_babe::BabeConfiguration

pub struct BabeConfiguration {
    pub slot_duration: u64,
    pub epoch_length: u64,
    pub c: (u64, u64),
    pub authorities: Vec<(AuthorityId, BabeAuthorityWeight)>,
    pub randomness: Randomness,
    pub allowed_slots: AllowedSlots,
}

Configuration data used by the BABE consensus engine.

Fields

slot_duration: u64

The slot duration in milliseconds for BABE. Currently, only the value provided by this type at genesis will be used.

Dynamic slot duration may be supported in the future.

epoch_length: u64

The duration of epochs in slots.

c: (u64, u64)

A constant value that is used in the threshold calculation formula. Expressed as a rational where the first member of the tuple is the numerator and the second is the denominator. The rational should represent a value between 0 and 1. In the threshold formula calculation, 1 - c represents the probability of a slot being empty.

authorities: Vec<(AuthorityId, BabeAuthorityWeight)>

The authorities

randomness: Randomness

The randomness

allowed_slots: AllowedSlots

Type of allowed slots.

Implementations

impl BabeConfiguration

pub fn slot_duration(&self) -> SlotDuration

Convenience method to get the slot duration as a SlotDuration value.

Trait Implementations

impl Clone for BabeConfiguration

fn clone(&self) -> BabeConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BabeConfiguration

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

Formats the value using the given formatter.

impl Decode for BabeConfiguration

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

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for BabeConfiguration

fn size_hint(&self) -> usize

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

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

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

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

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.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<BabeConfigurationV1> for BabeConfiguration

fn from(v1: BabeConfigurationV1) -> Self

Converts to this type from the input type.

impl PartialEq for BabeConfiguration

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for BabeConfiguration

type Identity = BabeConfiguration

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl EncodeLike for BabeConfiguration

impl Eq for BabeConfiguration

impl StructuralPartialEq for BabeConfiguration
