Expand description

A server handler for the DictionaryDrainIterator protocol.

See DictionaryDrainIterator for more details.

Required Methods§

Source

fn get_next( &mut self, request: Request<GetNext, ___T>, responder: Responder<GetNext, ___T>, ) -> impl Future<Output = ()> + Send

Returns the next batch of results for a [Dictionary.Drain] call, returning up to limit results. limit can be at most MAX_DICTIONARY_ITERATOR_CHUNK.

Each returned capability will be assigned a monotonically increasing CapabilityId starting from start_id.

In addition to the items, returns end_id, which is one more than the highest id reserved by [GetNext]. end_id can be used as the start_id for the next call to [GetNext].

If [GetNext] returns an error, the server will also close the channel.

Errors:

  • ID_ALREADY_EXISTS if some id in the range [start_id, limit) already exists in this store.
  • INVALID_ARGS if limit was 0 or greater than MAX_DICTIONARY_ITERATOR_CHUNK.

Provided Methods§

Source

fn on_unknown_interaction( &mut self, ordinal: u64, ) -> impl Future<Output = ()> + Send

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.
