Source client used in parachain heads synchronization loop.

Required Methods

fn ensure_synced<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<bool, Self::Error>> + Send + 'async_trait>>

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

Returns Ok(true) if client is in synced state.

fn parachain_head<'life0, 'async_trait>( &'life0 self, at_block: HeaderIdOf<P::SourceRelayChain>, ) -> Pin<Box<dyn Future<Output = Result<AvailableHeader<HeaderIdOf<P::SourceParachain>>, Self::Error>> + Send + 'async_trait>>

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

Get parachain head id at given block.

fn prove_parachain_head<'life0, 'async_trait>( &'life0 self, at_block: HeaderIdOf<P::SourceRelayChain>, ) -> Pin<Box<dyn Future<Output = Result<(ParaHeadsProof, ParaHash), Self::Error>> + Send + 'async_trait>>

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

Get parachain head proof at given block.
