Struct sc_finality_grandpa::FinalityProofProvider

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

Finality proof provider for serving network requests.

Implementations

impl<B, Block> FinalityProofProvider<B, Block>where Block: BlockT, B: Backend<Block>,

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, B: Backend<Block>,

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 in bytes.

pub fn prove_finality_proof( &self, block: NumberFor<Block>, collect_unknown_headers: bool ) -> Result<Option<FinalityProof<Block::Header>>, FinalityProofError>

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

If collect_unknown_headers is true, the finality proof will include all headers from the requested block until the block the justification refers to.

Trait Implementations

impl<BE: Clone, Block: Clone + BlockT> Clone for FinalityProofProvider<BE, Block>where Block::Hash: Clone,

fn clone(&self) -> FinalityProofProvider<BE, Block>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
