FallbackCLRSOracle

Gets the exchange rate between the underlying asset and the peg asset by using: the price from a Chainlink price feed or a Redstone Oracle with one of them being used as main source and the other one acting as a fallback if the main source fails for any reason. Reverts if fetched rate is 0.

constructor

constructor(string infoName_, uint8 mainSource_, struct ChainlinkStructs.ChainlinkConstructorParams chainlinkParams_, struct RedstoneStructs.RedstoneOracleData redstoneOracle_) public

sets the main source, Chainlink Oracle and Redstone Oracle data.

FALLBACK_ORACLE_MAIN_SOURCE

function FALLBACK_ORACLE_MAIN_SOURCE() public view returns (uint8)

which oracle to use as main source: - 1 = Chainlink ONLY (no fallback) - 2 = Chainlink with Redstone Fallback - 3 = Redstone with Chainlink Fallback
