Struct Accumulator

pub struct Accumulator<T: Config<I>, I: 'static> {
    pub value: T::Pulse,
    pub step: T::Pulse,
}

Internal accumulator structure for discrete XP pulse tracking.

This struct implements the accumulator pattern for reputation-based XP systems, where XP activities are tracked through discrete steps that accumulate towards threshold-based value increments. It serves as the core data structure for the pulse reputation system.

Fields

• value - The current accumulated XP value (reputation level)
• step - The current step progress towards the next value increment

Fields

value: T::Pulse

The current accumulated value representing the reputation level.

This field holds the meaningful accumulated result that represents the user’s reputation/heartbeat or XP level. It increments when step thresholds are reached through the discrete accumulation process.

step: T::Pulse

The current step progress towards the next value increment.

This field tracks intermediate fractional progress between value increments.

Steps accumulate until they reach a threshold defined by the stepper, at which point the value is incremented and steps are reset or adjusted.

Trait Implementations

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

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

Formats the value using the given formatter.

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

where T::Pulse: 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> Default for Accumulator<T, I>

fn default() -> Self

Creates a new accumulator with both value and step initialized to their default values (zero).

impl<T: Config<I>, I: 'static> Encode for Accumulator<T, I>

where T::Pulse: 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> MaxEncodedLen for Accumulator<T, I>

where T::Pulse: MaxEncodedLen,
