Crate bp_header_chain

Defines traits which represent a common interface for Substrate pallets which want to incorporate bridge functionality.

Modules

• justification
  Logic for checking GRANDPA Finality Proofs.
• storage_keys
  Storage keys of bridge GRANDPA pallet.

Structs

• AuthoritySet
  A GRANDPA Authority List and ID.
• GrandpaConsensusLogReader
  A struct that provides helper methods for querying the GRANDPA consensus log.
• HeaderFinalityInfo
  The finality-related info associated to a header.
• InitializationData
  Data required for initializing the GRANDPA bridge pallet.
• StoredHeaderData
  Header data that we’re storing on-chain.

Enums

• BridgeGrandpaCall
  A minimized version of pallet-bridge-grandpa::Call that can be used without a runtime.
• HeaderChainError
  Header chain error.

Traits

• ChainWithGrandpa
  Substrate-based chain that is using direct GRANDPA finality.
• ConsensusLogReader
  A trait that provides helper methods for querying the consensus log.
• FinalityProof
  Abstract finality proof that is justifying block finality.
• FindEquivocations
  Helper trait for finding equivocations in finality proofs.
• HeaderChain
  Substrate header chain, abstracted from the way it is stored.
• Parameter
  A type that can be used as a parameter in a dispatchable function.
• StoredHeaderDataBuilder
  Stored header data builder.

Functions

• max_expected_submit_finality_proof_arguments_size
  Returns maximal expected size of submit_finality_proof call arguments.

Type Aliases

• BridgeGrandpaCallOf
  The BridgeGrandpaCall used by a chain.
• HeaderGrandpaInfo
  Processed Grandpa-related info associated to a header.
• StoredHeaderGrandpaInfo
  Grandpa-related info associated to a header. This info can be saved to events.
