Struct GenericWorkItem

pub struct GenericWorkItem<Xt> {
    pub service: ServiceId,
    pub code_hash: CodeHash,
    pub payload: WorkPayload,
    pub refine_gas_limit: Gas,
    pub accumulate_gas_limit: Gas,
    pub import_segments: WorkItemImportsVec,
    pub extrinsics: Vec<Xt>,
    pub export_count: u16,
}

A definition of work to be done by the Refinement logic of a service and transformed into a WorkOutput for its Accumulation logic.

This is the generic version of the work-item, which is specialized depending on whether and how the extrinsic data is supplied.

Fields

service: ServiceId

Service identifier to which this work item relates.

code_hash: CodeHash

The service’s code hash at the time of reporting. This must be available in-core at the time of the lookup-anchor block.

payload: WorkPayload

Opaque data passed in to the service’s Refinement logic to describe its workload.

refine_gas_limit: Gas

Gas limit with which to execute this work item’s Refine logic.

accumulate_gas_limit: Gas

Gas limit with which to execute this work item’s Accumulate logic.

import_segments: WorkItemImportsVec

Sequence of imported data segments.

extrinsics: Vec<Xt>

Additional data available to the service’s Refinement logic while doing its workload.

export_count: u16

Number of segments exported by this work item.
