Expand description

The response type for the chain service.

Variants§

§

CompactHistory

The response for ChainSvcRequest::CompactHistory.

Fields

§block_ids: Vec<[u8; 32]>

A list of blocks IDs in our chain, starting with the most recent block, all the way to the genesis block.

These blocks should be in reverse chronological order, not every block is needed.

§cumulative_difficulty: u128

The current cumulative difficulty of the chain.

§

FindFirstUnknown(Option<(usize, usize)>)

The response for ChainSvcRequest::FindFirstUnknown.

Contains the index of the first unknown block and its expected height.

§

CumulativeDifficulty(u128)

The response for ChainSvcRequest::CumulativeDifficulty.

The current cumulative difficulty of our chain.

§

ValidateEntries

Fields

§valid: VecDeque<ChainEntry<N>>
§unknown: VecDeque<ChainEntry<N>>
