Struct ValidatorSetReport 

pub struct ValidatorSetReport<AccountId> {
    pub new_validator_set: Vec<AccountId>,
    pub id: u32,
    pub prune_up_to: Option<SessionIndex>,
    pub leftover: bool,
}

A report about a new validator set. This is sent from AH -> RC.

Fields

new_validator_set: Vec<AccountId>

The new validator set.

id: u32

The id of this validator set.

Is an always incrementing identifier for this validator set, the activation of which can be later pointed to in a SessionReport.

Implementation detail: within pallet-staking-async, this is always set to the planning-era (aka. CurrentEra).

prune_up_to: Option<SessionIndex>

Signal the relay chain that it can prune up to this session, and enough eras have passed.

This can always have a safety buffer. For example, whatever is a sane value, it can be value - 5.

leftover: bool

Same semantics as SessionReport::leftover.

Implementations

impl<AccountId> ValidatorSetReport<AccountId>

pub fn new_terminal( new_validator_set: Vec<AccountId>, id: u32, prune_up_to: Option<SessionIndex>, ) -> Self

A new instance of self that is terminal. This is useful when we want to send everything in one go.

pub fn merge(self, other: Self) -> Result<Self, UnexpectedKind>

Merge oneself with another instance.

pub fn split(self, chunk_size: usize) -> Vec<Self>

where AccountId: Clone,

Split self into chunks of chunk_size element.

Trait Implementations

impl<AccountId: Clone> Clone for ValidatorSetReport<AccountId>

fn clone(&self) -> ValidatorSetReport<AccountId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<AccountId: Debug> Debug for ValidatorSetReport<AccountId>

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

Formats the value using the given formatter.

impl<AccountId> Decode for ValidatorSetReport<AccountId>

where Vec<AccountId>: Decode,

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<AccountId> Display for ValidatorSetReport<AccountId>

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

Formats the value using the given formatter.

impl<AccountId> Encode for ValidatorSetReport<AccountId>

where Vec<AccountId>: Encode,

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<AccountId: PartialEq> PartialEq for ValidatorSetReport<AccountId>

fn eq(&self, other: &ValidatorSetReport<AccountId>) -> 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.

impl<AccountId> TypeInfo for ValidatorSetReport<AccountId>

where Vec<AccountId>: TypeInfo + 'static, AccountId: TypeInfo + 'static,

type Identity = ValidatorSetReport<AccountId>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
