Struct sc_finality_grandpa::FinalityProofFragment

pub struct FinalityProofFragment<Header: HeaderT> {
    pub block: Header::Hash,
    pub justification: Vec<u8>,
    pub unknown_headers: Vec<Header>,
    pub authorities_proof: Option<StorageProof>,
}

Single fragment of proof-of-finality.

Finality for block B is proved by providing:

1. the justification for the descendant block F;
2. headers sub-chain (B; F] if B != F;
3. proof of GRANDPA::authorities() if the set changes at block F.

Fields

block: Header::Hash

The hash of block F for which justification is provided.

justification: Vec<u8>

Justification of the block F.

unknown_headers: Vec<Header>

The set of headers in the range (U; F] that we believe are unknown to the caller. Ordered.

authorities_proof: Option<StorageProof>

Optional proof of execution of GRANDPA::authorities() at the block.
