Struct holochain_types::dna::HoloHash
source · pub struct HoloHash<T>where
T: HashType,{ /* private fields */ }
Expand description
A HoloHash contains a vector of 36 bytes representing a 32-byte blake2b hash plus 4 bytes representing a DHT location. It also contains a zero-sized type which specifies what it is a hash of.
There is custom de/serialization implemented in [ser.rs]
