Struct sc_finality_grandpa::FinalityProofProvider

pub struct FinalityProofProvider<BE, Block: BlockT> { /* fields omitted */ }

Finality proof provider for serving network requests.

Implementations

impl<B, Block: BlockT> FinalityProofProvider<B, Block> where
    B: Backend<Block> + Send + Sync + 'static, 

pub fn new(
    backend: Arc<B>,
    shared_authority_set: Option<SharedAuthoritySet<Block::Hash, NumberFor<Block>>>
) -> Self

Create new finality proof provider using:

• backend for accessing blockchain data;
• authority_provider for calling and proving runtime methods.
• shared_authority_set for accessing authority set data

pub fn new_for_service(
    backend: Arc<B>,
    shared_authority_set: Option<SharedAuthoritySet<Block::Hash, NumberFor<Block>>>
) -> Arc<Self>

Create new finality proof provider for the service using:

• backend for accessing blockchain data;
• storage_provider, which is generally a client.
• shared_authority_set for accessing authority set data

impl<B, Block> FinalityProofProvider<B, Block> where
    Block: BlockT,
    NumberFor<Block>: BlockNumberOps,
    B: Backend<Block> + Send + Sync + 'static, 

pub fn prove_finality(
    &self,
    block: NumberFor<Block>
) -> Result<Option<Vec<u8>>, FinalityProofError>

Prove finality for the given block number by returning a Justification for the last block of the authority set.
