Implementations

impl<'a> EvmCacheChainlinkReader<'a>

pub fn with_multicall_reads(self, enabled: bool) -> Self

Enable or disable direct/fork Multicall3 view batching.

pub async fn register_feed( &self, registry: &mut OracleRegistry, feed: Feed, ) -> Result<FeedId, OracleError>

Register a typed feed into an existing oracle registry.

pub async fn register_feeds( &self, registry: &mut OracleRegistry, feeds: Vec<Feed>, ) -> Result<Vec<OracleAdapterFeedSkip>, OracleError>

Register multiple Chainlink-compatible feeds, batching proxy reads when possible.

pub async fn register_config( &self, registry: &mut OracleRegistry, config: FeedConfig, ) -> Result<FeedId, OracleError>

Register a Chainlink-compatible feed config into an existing registry.

pub fn read_decimals(&self, proxy: Address) -> Result<u8, OracleError>

Read decimals() from a Chainlink-compatible proxy.

pub fn read_description(&self, proxy: Address) -> Result<String, OracleError>

Read description() from a Chainlink-compatible proxy.

pub fn read_version(&self, proxy: Address) -> Result<U256, OracleError>

Read version() from a Chainlink-compatible proxy.

pub fn read_latest_round_data( &self, proxy: Address, ) -> Result<RoundData, OracleError>

Read latestRoundData() from a Chainlink-compatible proxy.

pub fn read_aggregator( &self, proxy: Address, ) -> Result<Option<Address>, OracleError>

Best-effort read of the proxy’s current aggregator.

pub fn read_type_and_version( &self, aggregator: Address, ) -> Result<Option<String>, OracleError>

Best-effort read of an aggregator implementation typeAndVersion().
