Struct EntryInfo

pub struct EntryInfo<T: Config<I>, I: 'static = ()> {
    digest: EntryDigest<T>,
    shares: T::Shares,
    variant: T::Position,
}

Represents a single entry within an index.

Each entry maps a direct digest to a non-zero share allocation and a semantic variant. This allows index commitments to be proportionally distributed across multiple underlying digests.

Fields

digest: EntryDigest<T>

The direct digest identifying this entry.

shares: T::Shares

Number of shares (must be non-zero) associated with this entry.

variant: T::Position

Semantic variant/disposition of this entry (e.g. Affirmative, Contrary, etc).

Commitments placed through this entry are credited to the corresponding variant balance of the underlying direct digest.

Implementations

impl<T: Config<I>, I: 'static> EntryInfo<T, I>

pub fn new( digest: EntryDigest<T>, shares: T::Shares, variant: T::Position, ) -> Result<Self, DispatchError>

Creates a new EntryInfo for an index.

Validates that the provided shares are non-zero and that the variant is semantically valid.

Returns DispatchError if validation fails.

pub fn shares(&self) -> T::Shares

Return the share value of this entry.

DispatchError if inconsistency detected.

pub fn digest(&self) -> Digest<T>

Returns the direct digest associated with this entry.

pub fn variant(&self) -> T::Position

Returns the variant associated with this entry’s direct digest.

Trait Implementations

impl<T: Config<I>, I: 'static> Clone for EntryInfo<T, I>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Config<I>, I: 'static> Debug for EntryInfo<T, I>

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

Formats the value using the given formatter.

impl<T: Config<I>, I: 'static> Decode for EntryInfo<T, I>

where EntryDigest<T>: Decode, T::Shares: Decode, T::Position: 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<T: Config<I>, I: 'static> Encode for EntryInfo<T, I>

where EntryDigest<T>: Encode, T::Shares: Encode, T::Position: 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<T: Config<I>, I: 'static> From<EntryInfo<T, I>> for SlotInfo<T, I>

fn from(entry: EntryInfo<T, I>) -> Self

Converts an EntryInfo into a SlotInfo.

This is used when creating a pool from an index, as each index entry corresponds to a pool slot. The deposit-receipt is initialized to empty as slot doesn’t hold a commit currently.

Returns

A SlotInfo with the same digest, shares, and variant.

impl<T: Config<I>, I: 'static> MaxEncodedLen for EntryInfo<T, I>

where EntryDigest<T>: MaxEncodedLen, T::Shares: MaxEncodedLen, T::Position: MaxEncodedLen,

fn max_encoded_len() -> usize

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

impl<T: Config<I>, I: 'static> PartialEq for EntryInfo<T, I>

fn eq(&self, other: &Self) -> 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<T, I> TypeInfo for EntryInfo<T, I>

where EntryDigest<T>: TypeInfo + 'static, T::Shares: TypeInfo + 'static, T::Position: TypeInfo + 'static, T: Config<I> + 'static, I: 'static,

type Identity = EntryInfo<T, I>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<T: Config<I>, I: 'static> DecodeWithMemTracking for EntryInfo<T, I>

where EntryDigest<T>: DecodeWithMemTracking, T::Shares: DecodeWithMemTracking, T::Position: DecodeWithMemTracking,

impl<T: Config<I>, I: 'static> EncodeLike for EntryInfo<T, I>

where EntryDigest<T>: Encode, T::Shares: Encode, T::Position: Encode,

impl<T: Config<I>, I: 'static> Eq for EntryInfo<T, I>
