Struct CallbackSink 

pub struct CallbackSink<F> { /* private fields */ }

A sink that invokes a user-supplied async function for each batch.

The callback receives a slice of MarketEvent and can process them however it likes. This is the simplest way to wire up custom logic without implementing EventSink directly.

Implementations

impl<F> CallbackSink<F>

pub fn new(name: impl Into<String>, callback: F) -> Self

Create a new callback sink.

The name is used for logging and debugging.

Trait Implementations

impl<F, Fut> EventSink for CallbackSink<F>

where F: Fn(Vec<MarketEvent>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<()>> + Send + 'static,

fn accept<'life0, 'life1, 'async_trait>( &'life0 self, events: &'life1 [MarketEvent], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Accept a batch of market events.

fn name(&self) -> &str

A human-readable name for logging and debugging.

fn shutdown<'life0, 'async_trait>( &'life0 self, _token: CancellationToken, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Called when the loader is shutting down.
