Information about a core which is currently occupied.

Fields

next_up_on_available: Option<ScheduledCore>

If this core is freed by availability, this is the assignment that is next up on this core, if any. None if there is nothing queued for this core.

occupied_since: N

The relay-chain block number this began occupying the core at.

time_out_at: N

The relay-chain block this will time-out at, if any.

next_up_on_time_out: Option<ScheduledCore>

If this core is freed by being timed-out, this is the assignment that is next up on this core. None if there is nothing queued for this core or there is no possibility of timing out.

availability: BitVec<u8, Lsb0>

A bitfield with 1 bit for each validator in the set. 1 bits mean that the corresponding validators has attested to availability on-chain. A 2/3+ majority of 1 bits means that this will be available.

group_responsible: GroupIndex

The group assigned to distribute availability pieces of this candidate.

candidate_hash: CandidateHash

The hash of the candidate occupying the core.

candidate_descriptor: CandidateDescriptor<H>

The descriptor of the candidate occupying the core.

Implementations

impl<H, N> OccupiedCore<H, N>

pub fn para_id(&self) -> Id

Get the Para currently occupying this core.

Trait Implementations

impl<H, N> Clone for OccupiedCore<H, N>where H: Clone, N: Clone,

fn clone(&self) -> OccupiedCore<H, N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<H, N> Debug for OccupiedCore<H, N>where H: Debug, N: Debug,

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

Formats the value using the given formatter.

impl<H, N> Decode for OccupiedCore<H, N>where N: Decode, CandidateDescriptor<H>: Decode,

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

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<H, N> Encode for OccupiedCore<H, N>where N: Encode, CandidateDescriptor<H>: Encode,

fn size_hint(&self) -> usize

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

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 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<H, N> PartialEq<OccupiedCore<H, N>> for OccupiedCore<H, N>where H: PartialEq<H>, N: PartialEq<N>,

fn eq(&self, other: &OccupiedCore<H, N>) -> 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<H, N> TypeInfo for OccupiedCore<H, N>where N: TypeInfo + 'static, CandidateDescriptor<H>: TypeInfo + 'static, H: TypeInfo + 'static,

type Identity = OccupiedCore<H, N>

The type identifying for which type info is provided.

fn type_info() -> Type<MetaForm>

Returns the static type identifier for Self.
