CallbackConsumer

Allows creating one-time requests for off-chain container compute, delivered via callback

Inherits BaseConsumer to inherit functions to receive container compute responses and emit container inputs

State Variables

subscriptionInputs

subscriptionId => callback input data

Could be restricted to private visibility but kept internal for better testing/downstream modification support

mapping(uint32 => bytes) internal subscriptionInputs;

Functions

constructor

Initialize new CallbackConsumer

constructor(address registry) BaseConsumer(registry);

Parameters

Name	Type	Description
`registry`	`address`	registry address

_requestCompute

Creates a one-time request for off-chain container compute via callback

Under the hood, creates a new subscription at the Infernet coordinator, with period == 0 and frequency == 1, effectively initializing a subscription valid immediately and only for 1 interval

function _requestCompute(
    string memory containerId,
    bytes memory inputs,
    uint16 redundancy,
    address paymentToken,
    uint256 paymentAmount,
    address wallet,
    address verifier
) internal returns (uint32);

Parameters

Name	Type	Description
`containerId`	`string`	compute container identifier(s) used by off-chain Infernet node
`inputs`	`bytes`	optional container inputs
`redundancy`	`uint16`	number of unique responding Infernet nodes
`paymentToken`	`address`	If providing payment for compute, payment token address (address(0) for ETH, else ERC20 contract address)
`paymentAmount`	`uint256`	If providing payment for compute, payment in `paymentToken` per compute request fulfillment
`wallet`	`address`	If providing payment for compute, Infernet `Wallet` address; this contract must be approved spender of `Wallet`
`verifier`	`address`	optional verifier contract to restrict payment based on response proof verification

Returns

Name	Type	Description
`<none>`	`uint32`	subscription ID of newly-created one-time subscription

getContainerInputs

View function to broadcast dynamic container inputs to off-chain Infernet nodes

Modified from BaseConsumer to expose callback input data, indexed by subscriptionId

function getContainerInputs(uint32 subscriptionId, uint32 interval, uint32 timestamp, address caller)
    external
    view
    override
    returns (bytes memory);

Parameters

Name	Type	Description
`subscriptionId`	`uint32`	subscription ID to collect container inputs for
`interval`	`uint32`	subscription interval to collect container inputs for
`timestamp`	`uint32`	timestamp at which container inputs are collected
`caller`	`address`	calling address
