Struct holochain_types::dna::HoloHashed
source · pub struct HoloHashed<C>where
C: HashableContent,{
pub content: C,
pub hash: HoloHash<<C as HashableContent>::HashType>,
}
Expand description
Represents some piece of content along with its hash representation, so that hashes need not be calculated multiple times. Provides an easy constructor which consumes the content.
Fields§
§content: C
The content which is hashed of type C.
hash: HoloHash<<C as HashableContent>::HashType>
The hash of the content C.
