Struct sc_finality_grandpa::warp_proof::NetworkProvider

pub struct NetworkProvider<Block: BlockT, Backend: ClientBackend<Block>> where
    NumberFor<Block>: BlockNumberOps,  { /* fields omitted */ }

Implements network API for warp sync.

Implementations

impl<Block: BlockT, Backend: ClientBackend<Block>> NetworkProvider<Block, Backend> where
    NumberFor<Block>: BlockNumberOps, 

pub fn new(
    backend: Arc<Backend>,
    authority_set: SharedAuthoritySet<Block::Hash, NumberFor<Block>>
) -> Self

Create a new istance for a given backend and authority set.

Trait Implementations

impl<Block: BlockT, Backend: ClientBackend<Block>> WarpSyncProvider<Block> for NetworkProvider<Block, Backend> where
    NumberFor<Block>: BlockNumberOps, 

fn generate(
    &self,
    start: Block::Hash
) -> Result<EncodedProof, Box<dyn Error + Send + Sync>>

Generate proof starting at given block hash. The proof is accumulated until maximum proof size is reached.

fn verify(
    &self,
    proof: &EncodedProof,
    set_id: SetId,
    authorities: AuthorityList
) -> Result<VerificationResult<Block>, Box<dyn Error + Send + Sync>>

Verify warp proof agains current set of authorities.

fn current_authorities(&self) -> AuthorityList

Get current list of authorities. This is supposed to be genesis authorities when starting sync.
