Struct polkadot_node_primitives::BabeEpochConfiguration

pub struct BabeEpochConfiguration {
    pub c: (u64, u64),
    pub allowed_slots: AllowedSlots,
}

Configuration data used by the BABE consensus engine that may change with epochs.

Fields

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.

allowed_slots: AllowedSlots

Whether this chain should run with secondary slots, which are assigned in round-robin manner.

Trait Implementations

impl Clone for BabeEpochConfiguration

fn clone(&self) -> BabeEpochConfiguration

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BabeEpochConfiguration

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

Formats the value using the given formatter.

impl Decode for BabeEpochConfiguration

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

Attempt to deserialise the value from input.

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<'de> Deserialize<'de> for BabeEpochConfiguration

fn deserialize<__D>(
    __deserializer: __D
) -> Result<BabeEpochConfiguration, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for BabeEpochConfiguration

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

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

fn size_hint(&self) -> usize

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    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<NextConfigDescriptor> for BabeEpochConfiguration

fn from(desc: NextConfigDescriptor) -> BabeEpochConfiguration

Converts to this type from the input type.

impl MaxEncodedLen for BabeEpochConfiguration

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl PartialEq<BabeEpochConfiguration> for BabeEpochConfiguration

fn eq(&self, other: &BabeEpochConfiguration) -> 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 Serialize for BabeEpochConfiguration

fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for BabeEpochConfiguration

type Identity = BabeEpochConfiguration

The type identifying for which type info is provided.

fn type_info() -> Type<MetaForm>

Returns the static type identifier for Self.

impl EncodeLike<BabeEpochConfiguration> for BabeEpochConfiguration

impl Eq for BabeEpochConfiguration

impl StructuralEq for BabeEpochConfiguration
