Struct hdk::prelude::HoloHashed

pub struct HoloHashed<C> where
    C: HashableContent, {
    pub content: C,
    pub hash: HoloHash<<C as HashableContent>::HashType>,
}

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.

Implementations
