HeaderEntry

mwc_core::core::block

Struct HeaderEntry 

Source 
pub struct HeaderEntry {
    pub hash: Hash,
    /* private fields */
}
Expand description

Header entry for storing in the header MMR. Note: we hash the block header itself and maintain the hash in the entry. This allows us to lookup the original header from the db as necessary.

Fields§

§hash: Hash

Hash for the BlockHeader
