impl<C> PreimageOracleClient for OracleReader<C>

where C: Channel + Send + Sync,

fn get<'life0, 'async_trait>( &'life0 self, key: PreimageKey, ) -> Pin<Box<dyn Future<Output = PreimageOracleResult<Vec<u8>>> + Send + 'async_trait>>

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

Get the data corresponding to the currently set key from the host. Return the data in a new heap allocated Vec<u8>
