This contract is used to get the price of the asset that corresponds to the stored feed ID.

Is implemented by the OracleMiddlewareWithRedstone contract.

State Variables

REDSTONE_HEARTBEAT

Gets the interval between two Redstone price updates.

uint48 public constant REDSTONE_HEARTBEAT = 10 seconds;

REDSTONE_DECIMALS

Gets the number of decimals for prices contained in Redstone price updates.

uint8 public constant REDSTONE_DECIMALS = 8;

_redstoneFeedId

The ID of the Redstone price feed.

bytes32 internal immutable _redstoneFeedId;

_redstoneRecentPriceDelay

The maximum age of a price to be considered recent.

uint48 internal _redstoneRecentPriceDelay = 45 seconds;

Functions

constructor

constructor(bytes32 redstoneFeedId);

Parameters

getRedstoneFeedId

Gets the ID of the Redstone price feed.

function getRedstoneFeedId() external view returns (bytes32 feedId_);

Returns

getRedstoneRecentPriceDelay

Gets the maximum age of a price to be considered recent.

function getRedstoneRecentPriceDelay() external view returns (uint48 delay_);

Returns

validateTimestamp

Used by the Redstone contract internally, we override it to allow all timestamps.

function validateTimestamp(uint256) public pure override(IRedstoneOracle, RedstoneConsumerBase);

Parameters

_getFormattedRedstonePrice

Gets the price of the asset from Redstone, formatted to the specified number of decimals.

Redstone automatically retrieves data from the end of the calldata, no need to pass the pointer.

function _getFormattedRedstonePrice(uint128 targetTimestamp, uint256 middlewareDecimals)
    internal
    view
    returns (RedstonePriceInfo memory formattedPrice_);

Parameters

Returns

_extractPriceUpdateTimestamp

Extract the timestamp from the price update.

extractedTimestamp_ is a timestamp in seconds.

function _extractPriceUpdateTimestamp() internal pure returns (uint48 extractedTimestamp_);

Returns
