impl H256
[src]
Utilities using the byteorder
crate.
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.

Note
For hash type with less than 8 bytes the missing bytes are interpreted as being zero.
pub fn from_low_u64_be(val: u64) -> H256
[src]
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.
pub fn from_low_u64_le(val: u64) -> H256
[src]
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.
pub fn from_low_u64_ne(val: u64) -> H256
[src]
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.

crate.
pub fn randomize_using<R>(&mut self, rng: &mut R) where
R: Rng + ?Sized,
[src]
R: Rng + ?Sized,

to a cryptographically random value using the
given random number generator.
pub fn randomize(&mut self)
[src]

to a cryptographically random value.
pub fn random_using<R>(rng: &mut R) -> H256 where
R: Rng + ?Sized,
[src]
R: Rng + ?Sized,
Create a new hash with cryptographically random content using the given random number generator.
pub fn random() -> H256
[src]
Create a new hash with cryptographically random content.
