D: Deserializer<'de>,
fn deserialize<D>( deserializer: D ) -> Result<Hash256Bits, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,
Deserialize this value from the given Serde deserializer. Read more
§impl From<[u8; 32]> for Hash256Bits
impl From<[u8; 32]> for Hash256Bits
Trivial new type derivation. Secrets should have private interiors and be constructed directly from fixed length arrays of known length.
§fn from(b: [u8; 32]) -> Hash256Bits
fn from(b: [u8; 32]) -> Hash256Bits
Converts to this type from the input type.
§impl PartialEq<Hash256Bits> for Hash256Bits
impl PartialEq<Hash256Bits> for Hash256Bits
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: &Hash256Bits) -> bool
fn eq(&self, other: &Hash256Bits) -> bool
This method tests for
self
and other
values to be equal, and is used
by ==
.§impl Serialize for Hash256Bits

§fn serialize<S>(
&self,
serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>where
S: Serializer,
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. Read more
§impl TryFrom<&[u8]> for Hash256Bits
impl TryFrom<&[u8]> for Hash256Bits
§type Error = SecurePrimitiveError
type Error = SecurePrimitiveError
The type returned in the event of a conversion error.
§fn try_from(
slice: &[u8]
) -> Result<Hash256Bits, <Hash256Bits as TryFrom<&[u8]>>::Error>
fn try_from( slice: &[u8] ) -> Result<Hash256Bits, <Hash256Bits as TryFrom<&[u8]>>::Error>
Performs the conversion.
