Struct NonZeroHash 

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

The primitive hash that among other things is used to reference items, types, and native functions.

Examples

use rune::Hash;

assert!(Hash::index(0).as_non_empty().is_some());

Implementations

impl NonZeroHash

pub const fn get(self) -> Hash

Get the value as a hash.

Examples

use rune::Hash;

let hash = Hash::index(0).as_non_empty().ok_or("expected non-empty")?;
assert_eq!(hash.get(), Hash::index(0));

impl PartialEq<Hash> for NonZeroHash

fn eq(&self, other: &Hash) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
