Trait OrderBookMap 

pub trait OrderBookMap: Clone {
    type Key;

    // Required methods
    fn keys(&self) -> impl Iterator<Item = &Self::Key>;
    fn find(&self, key: &Self::Key) -> Option<Arc<RwLock<OrderBook>>>;
}

Collection of shared-state Instrument OrderBooks. Manage the local books using the super::manager module, and then clone the map for viewing the up to date OrderBooks elsewhere.

See OrderBookMapSingle and OrderBookMapMulti for implementations.

Required Associated Types

type Key

Required Methods

fn keys(&self) -> impl Iterator<Item = &Self::Key>

Return an Iterator over the OrderBookMap Keys (eg/ InstrumentKey).

fn find(&self, key: &Self::Key) -> Option<Arc<RwLock<OrderBook>>>

Attempt to find the OrderBook associated with the provided Key.

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.
