Crate finality_relay

This crate has single entrypoint to run synchronization loop that is built around finality proofs, as opposed to headers synchronization loop, which is built around headers. The headers are still submitted to the target node, but are treated as auxiliary data as we are not trying to submit all source headers to the target node.

Structs

• FinalityProofsBuf
  Source finality proofs buffer.
• FinalityProofsStream
  Source finality proofs stream that may be restarted.
• FinalitySyncParams
  Finality proof synchronization loop parameters.
• SyncLoopMetrics
  Headers sync metrics.

Enums

• HeadersToRelay
  Type of headers that we relay.

Traits

• FinalityPipeline
  Base finality pipeline.
• FinalitySyncPipeline
  Finality proofs synchronization pipeline.
• SourceClient
  Source client used in finality synchronization loop.
• SourceClientBase
  Source client used in finality related loops.
• SourceHeader
  Header that we’re receiving from source node.
• TargetClient
  Target client used in finality synchronization loop.

Functions

• metrics_prefix
  Return prefix that will be used by default to expose Prometheus metrics of the finality proofs sync loop.
• run
  Run finality proofs synchronization loop.
