Struct DParameter

pub struct DParameter {
    pub num_permissioned_candidates: u16,
    pub num_registered_candidates: u16,
}

Parameter controlling the number and proportion of registered and permissioned candidates selected into a Partner Chain committee, used by the Ariadne family of selection algorithms.

The core idea behind the D-Param is to enable a Partner Chain to bootstrap its operation by relying on a hand-picked set of trusted block producers for security, and to later incrementally shift block production onto trustless network participants as the chain grows and it becomes harder for malicious actors to manipulate the chain.

Fields

num_permissioned_candidates: u16

Expected number of permissioned candidates selected for a committee

num_registered_candidates: u16

Expected number of registered candidates selected for a committee

Implementations

impl DParameter

pub fn new( num_permissioned_candidates: u16, num_registered_candidates: u16, ) -> Self

Creates a new DParameter from member values

Trait Implementations

impl Clone for DParameter

fn clone(&self) -> DParameter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DParameter

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

Formats the value using the given formatter.

impl Decode for DParameter

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 DParameter

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 Hash for DParameter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl MaxEncodedLen for DParameter

fn max_encoded_len() -> usize

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

impl PartialEq for DParameter

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

Tests for self and other values to be equal, and is used by ==.

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for DParameter

type Identity = DParameter

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl DecodeWithMemTracking for DParameter

impl EncodeLike for DParameter

impl Eq for DParameter

impl StructuralPartialEq for DParameter
