Struct polkadot_primitives::v8::ChunkIndex

pub struct ChunkIndex(pub u32);

Index of an availability chunk.

The underlying type is identical to ValidatorIndex, because the number of chunks will always be equal to the number of validators. However, the chunk index held by a validator may not always be equal to its ValidatorIndex, so we use a separate type to make code easier to read.

Trait Implementations

impl Clone for ChunkIndex

fn clone(&self) -> ChunkIndex

Returns a copy of the value.

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

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

Formats the value using the given formatter.

impl Decode for ChunkIndex

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 ChunkIndex

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode for ChunkIndex

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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<ChunkIndex> for ValidatorIndex

fn from(c_index: ChunkIndex) -> Self

Converts to this type from the input type.

impl From<ValidatorIndex> for ChunkIndex

fn from(v_index: ValidatorIndex) -> Self

Converts to this type from the input type.

impl From<u32> for ChunkIndex

fn from(n: u32) -> Self

Converts to this type from the input type.

impl Hash for ChunkIndex

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,

impl Ord for ChunkIndex

fn cmp(&self, other: &ChunkIndex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ChunkIndex

fn eq(&self, other: &ChunkIndex) -> 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.

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

This method tests greater than (for self and other) and is used by the > operator.

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