Expand description

For the purposes of constructing unused handlers.

Fields§

§phantom: PhantomData<E>

Trait Implementations§

source§

impl<E> Handler for UnusedHandler<E>where E: Send,

§

type Envelope = E

The envelope processed by the handler.
source§

fn process<'life0, 'async_trait>( &'life0 mut self, _envelope: Self::Envelope ) -> Pin<Box<dyn Future<Output = Result<(), HandlerError>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Process an envelope. A handler’s result is “completed” where envelopes are processed upon the previous one having been processed successfully.

Auto Trait Implementations§

impl<E> RefUnwindSafe for UnusedHandler<E>where E: RefUnwindSafe,

§

impl<E> Send for UnusedHandler<E>where E: Send,

§

impl<E> Sync for UnusedHandler<E>where E: Sync,

§

impl<E> Unpin for UnusedHandler<E>where E: Unpin,

§

impl<E> UnwindSafe for UnusedHandler<E>where E: UnwindSafe,
