Trait WarpSyncProvider

    fn current_authorities(&self) -> AuthorityList;
}

Warp sync backend. Handles retrieving and verifying warp sync proofs.

Required Methods

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 against current set of authorities.

fn current_authorities(&self) -> AuthorityList

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