Source client used in finality synchronization loop.

Required Methods

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

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

Get best finalized block number.

fn header_and_finality_proof<'life0, 'async_trait>( &'life0 self, number: P::Number, ) -> Pin<Box<dyn Future<Output = Result<(P::Header, Option<P::FinalityProof>), Self::Error>> + Send + 'async_trait>>

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

Get canonical header and its finality proof by number.

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.
