Struct hdk::prelude::dependencies::holochain_integrity_types::Hash512Bits

pub struct Hash512Bits(_);

512 Bit generic hash.

Trait Implementations

impl AsRef<[u8]> for Hash512Bits

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for Hash512Bits

The only meaningful debug information for a cryptograhpic secret is the literal bytes. Also, encodings like base64 are not constant time so debugging could open some weird side channel issue trying to be ‘human friendly’. It seems better to never try to encode secrets.

Note that when using this crate with feature “subtle-encoding”, a hex representation will be used.

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Hash512Bits

fn deserialize<D>(
    deserializer: D
) -> Result<Hash512Bits, <D as Deserializer<'de>>::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<[u8; 64]> for Hash512Bits

Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.

fn from(b: [u8; 64]) -> Hash512Bits

Converts to this type from the input type.

impl PartialEq<Hash512Bits> for Hash512Bits

Constant time equality check. This mitigates timing attacks where a remote agent can reverse engineer data by measuring tiny changes in latency associated with optimised equality checks. More matching bytes = more latency = vulnerability. This type of attack has been successfully demonstrated over a network despite varied latencies.

fn eq(&self, other: &Hash512Bits) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Hash512Bits

fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for Hash512Bits

type Error = SecurePrimitiveError

The type returned in the event of a conversion error.

fn try_from(
    slice: &[u8]
) -> Result<Hash512Bits, <Hash512Bits as TryFrom<&[u8]>>::Error>

Performs the conversion.

impl TryFrom<Vec<u8, Global>> for Hash512Bits

type Error = SecurePrimitiveError

The type returned in the event of a conversion error.

fn try_from(
    v: Vec<u8, Global>
) -> Result<Hash512Bits, <Hash512Bits as TryFrom<Vec<u8, Global>>>::Error>

Performs the conversion.
