[−][src]Struct solana_libra_crypto::hash::HashValue
Output value of our hash function. Intentionally opaque for safety and modularity.
Methods
impl HashValue
[src]
pub const LENGTH: usize
[src]
The length of the hash in bytes.
pub const LENGTH_IN_BITS: usize
[src]
The length of the hash in bits.
pub const LENGTH_IN_NIBBLES: usize
[src]
The length of the hash in nibbles.
pub fn new(hash: [u8; 32]) -> Self
[src]
Create a new HashValue
from a byte array.
pub fn from_slice(src: &[u8]) -> Result<Self>
[src]
Create from a slice (e.g. retrieved from storage).
pub fn to_vec(&self) -> Vec<u8>
[src]
Dumps into a vector.
pub fn zero() -> Self
[src]
Creates a zero-initialized instance.
pub fn is_zero(&self) -> bool
[src]
Check if the hash value is zero.
pub fn random() -> Self
[src]
Create a cryptographically random instance.
pub fn random_with_rng<R: Rng>(rng: &mut R) -> Self
[src]
Creates a random instance with given rng. Useful in unit tests.
pub fn from_sha3_256(buffer: &[u8]) -> Self
[src]
Convenience function to compute a sha3-256 HashValue of the buffer. It will handle hasher creation, data feeding and finalization.
pub fn iter_bits(&self) -> HashValueBitIterator
[src]
Returns a HashValueBitIterator
over all the bits that represent this HashValue
.
pub fn common_prefix_bits_len(&self, other: HashValue) -> usize
[src]
Returns the length of common prefix of self
and other
in bits.
pub fn common_prefix_nibbles_len(&self, other: HashValue) -> usize
[src]
Returns the length of common prefix of self
and other
in nibbles.
pub fn get_nibble(&self, index: usize) -> Nibble
[src]
Returns the index
-th nibble.
pub fn short_str(&self) -> String
[src]
Returns first SHORT_STRING_LENGTH bytes as String in hex
