Trait InstrumentData

pub trait InstrumentData
where
    Self: Clone + Debug + Send + Sync,
{
    type Key: Debug + Clone + Eq + Send + Sync;

    // Required methods
    fn key(&self) -> &Self::Key;
    fn kind(&self) -> &MarketDataInstrumentKind;
}

Instrument related data that defines an associated unique Id.

Verbose InstrumentData is often used to subscribe to market data feeds, but it’s unique Id can then be used to key consumed MarketEvents, significantly reducing duplication in the case of complex instruments (eg/ options).

Required Associated Types

type Key: Debug + Clone + Eq + Send + Sync

Required Methods

fn key(&self) -> &Self::Key

fn kind(&self) -> &MarketDataInstrumentKind

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
