Struct Hash 

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

A link in a stream’s hash chain: SHA-256 over the previous link and the entry at this position (see crate::chain).

Implementations

impl Hash

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Wraps thirty-two bytes.

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

The thirty-two bytes.

pub fn short(&self) -> String

The first eight hex digits - enough to tell hashes apart in a listing, never enough to compare them.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
