Struct HoloHashed

pub struct HoloHashed<C: HashableContent> {
    pub content: C,
    pub hash: HoloHashOf<C>,
}

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: HoloHashOf<C>

The hash of the content C.

Implementations

impl<C> HoloHashed<C>

pub fn as_content(&self) -> &C

Accessor for content

pub fn into_content(self) -> C

Convert to content

pub fn into_inner(self) -> (C, HoloHashOf<C>)

Deconstruct as a tuple
