Expand description
Dynamic map of Drift market oracle data
Caller can subscribe to some subset of markets for Ws backed updates
Alternatively, the caller may drive the map by calling sync
periodically
Fields§
§oraclemap: Arc<DashMap<(Pubkey, u8), Oracle, RandomState>>
Oracle data keyed by pubkey and source
oracle_by_market: ReadOnlyView<MarketId, (Pubkey, OracleSource), RandomState>
Oracle (pubkey, source) by MarketId (immutable)
Implementations§
Source§impl OracleMap
impl OracleMap
pub const SUBSCRIPTION_ID: &'static str = "oraclemap"
Sourcepub fn new(
pubsub_client: Arc<PubsubClient>,
all_oracles: &[(MarketId, Pubkey, OracleSource)],
commitment: CommitmentConfig,
) -> Self
pub fn new( pubsub_client: Arc<PubsubClient>, all_oracles: &[(MarketId, Pubkey, OracleSource)], commitment: CommitmentConfig, ) -> Self
Create a new OracleMap
rpc_client
- Shared RPC client instancepubsub_client
- Shared Pubsub client instanceall_oracles
- Exhaustive list of all Drift oracle pubkeys and source by market
Sourcepub async fn subscribe(&self, markets: &[MarketId]) -> SdkResult<()>
pub async fn subscribe(&self, markets: &[MarketId]) -> SdkResult<()>
Subscribe to oracle updates for given markets
Can be called multiple times to subscribe to additional markets
Panics
If the market
oracle pubkey is not loaded
Sourcepub fn unsubscribe(&self, markets: &[MarketId]) -> SdkResult<()>
pub fn unsubscribe(&self, markets: &[MarketId]) -> SdkResult<()>
Unsubscribe from oracle updates for the given markets
Sourcepub fn unsubscribe_all(&self) -> SdkResult<()>
pub fn unsubscribe_all(&self) -> SdkResult<()>
Unsubscribe from all oracle updates
Sourcepub async fn sync(&self, markets: &[MarketId], rpc: &RpcClient) -> SdkResult<()>
pub async fn sync(&self, markets: &[MarketId], rpc: &RpcClient) -> SdkResult<()>
Fetches account data for each market oracle set by markets
This may be invoked manually to resync oracle data for some set of markets
Sourcepub fn is_subscribed(&self, market: &MarketId) -> bool
pub fn is_subscribed(&self, market: &MarketId) -> bool
Returns true if the oraclemap has a subscription for market
Sourcepub fn current_perp_oracle(&self, market_index: u16) -> Option<Pubkey>
pub fn current_perp_oracle(&self, market_index: u16) -> Option<Pubkey>
Get the address of a perp market oracle
Sourcepub fn current_spot_oracle(&self, market_index: u16) -> Option<Pubkey>
pub fn current_spot_oracle(&self, market_index: u16) -> Option<Pubkey>
Get the address of a spot market oracle
Sourcepub fn get_by_market(&self, market: &MarketId) -> Option<Oracle>
pub fn get_by_market(&self, market: &MarketId) -> Option<Oracle>
Return Oracle data by market, if known
pub fn values(&self) -> Vec<Oracle>
pub fn get_latest_slot(&self) -> u64
