Represents a capability to receive message from a Stream.

Required methods

#[must_use]fn handle<'life0, 'life1, 'async_trait>(
    &'life0 mut self,
    item: T,
    ctx: &'life1 mut Context<Self>
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, [src]

The method called when the next item received from a Stream.

If you need chunks here (group multiple items into chunks) than wrap your stream with ready_chunks method.

Provided methods

#[must_use]fn finished<'life0, 'life1, 'async_trait>(
    &'life0 mut self,
    _ctx: &'life1 mut Context<Self>
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: Send + 'async_trait, [src]

When the stream consumed completely.

Called after the last item in the stream only.

#[must_use]fn task_failed<'life0, 'life1, 'async_trait>(
    &'life0 mut self,
    err: TaskError,
    _ctx: &'life1 mut Context<Self>
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: Send + 'async_trait, [src]

The stream was failed.

#[must_use]fn task_finished<'life0, 'life1, 'async_trait>(
    &'life0 mut self,
    _ctx: &'life1 mut Context<Self>
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: Send + 'async_trait, [src]

When the stream task was finished sucessfully.

You should prefer to use finished instead of this, because it’s service event with the high-priority and it can overtake ordinary stream items.
