[]Struct solana_libra_nextgen_crypto::HashValue

pub struct HashValue { /* fields omitted */ }

Output value of our hash function. Intentionally opaque for safety and modularity.

Methods

impl HashValue

pub const LENGTH: usize

The length of the hash in bytes.

pub const LENGTH_IN_BITS: usize

The length of the hash in bits.

pub fn new(hash: [u8; 32]) -> HashValue

Create a new HashValue from a byte array.

pub fn from_slice(src: &[u8]) -> Result<HashValue, Error>

Create from a slice (e.g. retrieved from storage).

pub fn to_vec(&self) -> Vec<u8>

Dumps into a vector.

pub fn zero() -> HashValue

Creates a zero-initialized instance.

pub fn is_zero(&self) -> bool

Check if the hash value is zero.

pub fn random() -> HashValue

Create a cryptographically random instance.

pub fn random_with_rng<R>(rng: &mut R) -> HashValue where
    R: Rng

Creates a random instance with given rng. Useful in unit tests.

pub fn len() -> usize

Get the size of the hash.

pub fn last_n_bytes(&self, bytes: usize) -> String

Get the last n bytes as a String.

pub fn iter_bits(&self) -> HashValueBitIterator

Returns a HashValueBitIterator over all the bits that represent this HashValue.

pub fn common_prefix_bits_len(&self, other: HashValue) -> usize

Returns the length of common prefix of self and other in bits.
