Struct Hash 

pub struct Hash(/* private fields */);

A hash; the 32-byte output of a hashing algorithm.

This struct is used most often in solana-sdk and related crates to contain a SHA-256 hash, but may instead contain a blake3 hash.

Implementations

impl Hash

pub const fn new_from_array(hash_array: [u8; 32]) -> Hash

pub fn new_unique() -> Hash

unique Hash for tests and benchmarks.

pub const fn to_bytes(&self) -> [u8; 32]

pub const fn as_bytes(&self) -> &[u8; 32]
