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.

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.
