Struct hdk::prelude::ChainHead

pub struct ChainHead {
    pub header_seq: u32,
    pub hash: HoloHash<Header>,
}

The header at the head of the complete chain. This is as far as this authority can see a chain with no gaps.

Fields

header_seq: u32

Sequence number of this chain head.

hash: HoloHash<Header>

Hash of this chain head
