Trait Implementations

impl<S: WebSocketSource> Service for WebsocketService<S>

fn start<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, symbols: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Starts the service, connecting to the WebSocket and subscribing to symbols.

fn stop<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stops the service, cancelling the WebSocket subscription.

where Self: 'async_trait, 'life0: 'async_trait,

impl<S: WebSocketSource> Source for WebsocketService<S>

fn get_prices<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, symbols: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Vec<Result<PriceInfo, Error>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Retrieves prices for the specified symbols from the cached prices.

fn get_price<'life0, 'life1, 'async_trait>( &'life0 self, symbol: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<PriceInfo, Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Asynchronously retrieves the price for a specified symbol.
