Target client used in equivocation detection loop.

Required Methods

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

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

Get the best finalized header number.

fn best_synced_header_hash<'life0, 'async_trait>( &'life0 self, at: P::TargetNumber, ) -> Pin<Box<dyn Future<Output = Result<Option<P::Hash>, Self::Error>> + Send + 'async_trait>>

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

Get the hash of the best source header known by the target at the provided block number.

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

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

Get the data stored by the target at the specified block for validating source finality proofs.

fn synced_headers_finality_info<'life0, 'async_trait>( &'life0 self, at: P::TargetNumber, ) -> Pin<Box<dyn Future<Output = Result<Vec<HeaderFinalityInfo<<P as FinalityPipeline>::FinalityProof, <P as EquivocationDetectionPipeline>::FinalityVerificationContext>>, Self::Error>> + Send + 'async_trait>>

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

Get the finality info associated to the source headers synced with the target chain at the specified 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.
