Struct holochain::core::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.
Implementations§

C: HashableContent,
impl<C> HoloHashed<C>where C: HashableContent,
sourcepub fn with_pre_hashed(
content: C,
hash: HoloHash<<C as HashableContent>::HashType>
) -> HoloHashed<C>
pub fn with_pre_hashed( content: C, hash: HoloHash<<C as HashableContent>::HashType> ) -> HoloHashed<C>
Combine content with its precalculated hash
sourcepub fn as_content(&self) -> &C
pub fn as_content(&self) -> &C
Accessor for content
sourcepub fn as_content_mut(&mut self) -> &mut C
pub fn as_content_mut(&mut self) -> &mut C
Mutable accessor for content. Only useful for heavily mocked/fixturated data in testing. Guaranteed the hash will no longer match the content if mutated.
sourcepub fn into_content(self) -> C
pub fn into_content(self) -> C
Convert to content
sourcepub fn into_inner(self) -> (C, HoloHash<<C as HashableContent>::HashType>)
pub fn into_inner(self) -> (C, HoloHash<<C as HashableContent>::HashType>)
Deconstruct as a tuple

sourcepub fn from_content_sync(content: C) -> HoloHashed<C>
pub fn from_content_sync(content: C) -> HoloHashed<C>
Compute the hash of this content and store it alongside
sourcepub fn verify_hash_sync(&self) -> Result<(), HoloHash<T>>
pub fn verify_hash_sync(&self) -> Result<(), HoloHash<T>>
Verify that the cached hash matches the content. Important to run this after e.g. deserialization.
