pub fn as_bytes_mut(&mut self) -> &mut [u8]ⓘNotable traits for &[u8]impl Read for &[u8]impl Write for &mut [u8]
Extracts a mutable byte slice containing the entire fixed hash.
sourcepub fn as_fixed_bytes(&self) -> &[u8; 32]
pub fn as_fixed_bytes(&self) -> &[u8; 32]

sourcepub fn as_fixed_bytes_mut(&mut self) -> &mut [u8; 32]
pub fn as_fixed_bytes_mut(&mut self) -> &mut [u8; 32]
Extracts a reference to the byte array containing the entire fixed hash.
sourcepub fn to_fixed_bytes(self) -> [u8; 32]
pub fn to_fixed_bytes(self) -> [u8; 32]
Returns the inner bytes array.
sourcepub fn as_mut_ptr(&mut self) -> *mut u8
pub fn as_mut_ptr(&mut self) -> *mut u8
Returns a mutable raw pointer to the value.
sourcepub fn assign_from_slice(&mut self, src: &[u8])
pub fn assign_from_slice(&mut self, src: &[u8])
sourcepub fn from_slice(src: &[u8]) -> Self
pub fn from_slice(src: &[u8]) -> Self
sourceimpl H256
impl H256
Utilities using the byteorder
crate.
sourcepub fn to_low_u64_be(&self) -> u64
pub fn to_low_u64_be(&self) -> u64
Returns the lowest 8 bytes interpreted as big-endian.
Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
sourcepub fn to_low_u64_le(&self) -> u64
pub fn to_low_u64_le(&self) -> u64
Returns the lowest 8 bytes interpreted as little-endian.
Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
sourcepub fn to_low_u64_ne(&self) -> u64
pub fn to_low_u64_ne(&self) -> u64
Returns the lowest 8 bytes interpreted as native-endian.
Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
sourcepub fn from_low_u64_be(val: u64) -> Self
pub fn from_low_u64_be(val: u64) -> Self
Creates a new hash type from the given u64
value.
Note
- The given
u64
value is interpreted as big endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
sourcepub fn from_low_u64_le(val: u64) -> Self
pub fn from_low_u64_le(val: u64) -> Self
Creates a new hash type from the given u64
value.
Note
- The given
u64
value is interpreted as little endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
sourcepub fn from_low_u64_ne(val: u64) -> Self
pub fn from_low_u64_ne(val: u64) -> Self
Creates a new hash type from the given u64
value.
Note
- The given
u64
value is interpreted as native endian. - Ignores the most significant bits of the given value if the hash type has less than 8 bytes.
sourceimpl H256
impl H256
Utilities using the rand
crate.
sourcepub fn randomize_using<R>(&mut self, rng: &mut R)where
R: Rng + ?Sized,
pub fn randomize_using<R>(&mut self, rng: &mut R)where
R: Rng + ?Sized,
Assign self
to a cryptographically random value using the
given random number generator.
sourcepub fn random_using<R>(rng: &mut R) -> Selfwhere
R: Rng + ?Sized,
pub fn random_using<R>(rng: &mut R) -> Selfwhere
R: Rng + ?Sized,
Create a new hash with cryptographically random content using the given random number generator.
