Struct polkadot_primitives::v8::async_backing::AsyncBackingParams

pub struct AsyncBackingParams {
    pub max_candidate_depth: u32,
    pub allowed_ancestry_len: u32,
}

Candidate’s acceptance limitations for asynchronous backing per relay parent.

Fields

max_candidate_depth: u32

The maximum number of para blocks between the para head in a relay parent and a new candidate. Restricts nodes from building arbitrary long chains and spamming other validators.

When async backing is disabled, the only valid value is 0.

allowed_ancestry_len: u32

How many ancestors of a relay parent are allowed to build candidates on top of.

When async backing is disabled, the only valid value is 0.

Trait Implementations

impl Clone for AsyncBackingParams

fn clone(&self) -> AsyncBackingParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AsyncBackingParams

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

Formats the value using the given formatter.

impl Decode for AsyncBackingParams

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<'de> Deserialize<'de> for AsyncBackingParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for AsyncBackingParams

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 PartialEq for AsyncBackingParams

fn eq(&self, other: &AsyncBackingParams) -> 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 AsyncBackingParams

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeInfo for AsyncBackingParams

type Identity = AsyncBackingParams

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl Copy for AsyncBackingParams

impl EncodeLike for AsyncBackingParams
