Trait Source 

pub trait Source<T: PipelineIO>: Data {
    // Required methods
    fn on_next<'life0, 'async_trait>(
        &'life0 self,
        data: T,
        __arg2: Token,
    ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
    fn set_edge(&self, edge: Edge<T>, _: Token) -> Result<(), PipelineError>;

    // Provided method
    fn link<S: Sink<T> + 'static>(
        &self,
        sink: Arc<S>,
    ) -> Result<Arc<S>, PipelineError> { ... }
}

A Source trait defines how data is emitted from a source to a downstream sink.

Required Methods

fn on_next<'life0, 'async_trait>( &'life0 self, data: T, __arg2: Token, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

fn set_edge(&self, edge: Edge<T>, _: Token) -> Result<(), PipelineError>

Provided Methods

fn link<S: Sink<T> + 'static>( &self, sink: Arc<S>, ) -> Result<Arc<S>, PipelineError>

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.
