Implementations
impl H160
pub const fn repeat_byte(byte: u8) -> H160
Returns a new fixed hash where all bits are set to the given byte.
pub const fn zero() -> H160
Returns a new zero-initialized fixed hash.
pub const fn len_bytes() -> usize
Returns the size of this hash in bytes.
pub fn as_bytes(&self) -> &[u8]
Extracts a byte slice containing the entire fixed hash.
pub fn as_bytes_mut(&mut self) -> &mut [u8]
Extracts a mutable byte slice containing the entire fixed hash.
pub const fn as_fixed_bytes(&self) -> &[u8; 20]
Extracts a reference to the byte array containing the entire fixed hash.
pub fn as_fixed_bytes_mut(&mut self) -> &mut [u8; 20]
Extracts a reference to the byte array containing the entire fixed hash.
pub const fn to_fixed_bytes(self) -> [u8; 20]
Returns the inner bytes array.
pub fn as_ptr(&self) -> *const u8
Returns a constant raw pointer to the value.
pub fn as_mut_ptr(&mut self) -> *mut u8
Returns a mutable raw pointer to the value.
pub fn assign_from_slice(&mut self, src: &[u8])
Assign the bytes from the byte slice src
to self
.
Note
The given bytes are interpreted in big endian order.
Panics
If the length of src
and the number of bytes in self
do not match.
pub fn from_slice(src: &[u8]) -> H160
Create a new fixed-hash from the given slice src
.
Note
The given bytes are interpreted in big endian order.
Panics
If the length of src
and the number of bytes in Self
do not match.
pub fn covers(&self, b: &H160) -> bool
Returns true
if all bits set in b
are also set in self
.
pub fn is_zero(&self) -> bool
Returns true
if no bits are set.
impl H160
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.
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.
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.
pub fn from_low_u64_be(val: u64) -> H160
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) -> H160
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) -> H160
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.
impl H160
Utilities using the rand
crate.
pub fn randomize_using<R>(&mut self, rng: &mut R) where
R: Rng + ?Sized,
R: Rng + ?Sized,
Assign self
to a cryptographically random value using the
given random number generator.
pub fn randomize(&mut self)
Assign self
to a cryptographically random value.
pub fn random_using<R>(rng: &mut R) -> H160 where
R: Rng + ?Sized,
R: Rng + ?Sized,
Create a new hash with cryptographically random content using the given random number generator.
pub fn random() -> H160
Create a new hash with cryptographically random content.
