SubscriptionConsumer

Allows creating recurring subscriptions for off-chain container compute

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

Functions

constructor

Initialize new SubscriptionConsumer

constructor(address registry) BaseConsumer(registry);

Parameters

Name	Type	Description
`registry`	`address`	registry address

_createComputeSubscription

Creates a recurring request for off-chain container compute via callback response

function _createComputeSubscription(
    string memory containerId,
    uint32 frequency,
    uint32 period,
    uint16 redundancy,
    bool lazy,
    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
`frequency`	`uint32`	max number of times to process subscription (i.e, `frequency == 1` is a one-time request)
`period`	`uint32`	period, in seconds, at which to progress each responding `interval`
`redundancy`	`uint16`	number of unique responding Infernet nodes
`lazy`	`bool`	whether to lazily store subscription responses in `Inbox`
`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 subscription

_cancelComputeSubscription

Cancels a created subscription

Can only cancel owned subscriptions (address(this) == Coordinator.subscriptions[subscriptionId].owner)

function _cancelComputeSubscription(uint32 subscriptionId) internal;

Parameters

Name	Type	Description
`subscriptionId`	`uint32`	ID of subscription to cancel
