Struct chain_storage::BlockInfo

pub struct BlockInfo {
    id: Value,
    parent_id: Value,
    chain_length: u32,
    parent_ref_count: u32,
    tags_ref_count: u32,
}

A structure that holds the information about a blocks, that is needed to maintain consistency of the storage. This include the ID of the blocks, the ID of its parent and the length of the block chain for the given block.

Fields

id: Value

parent_id: Value

chain_length: u32

parent_ref_count: u32

tags_ref_count: u32
