Struct zeros::ReadOnlyZeros

pub struct ReadOnlyZeros(pub Zeros);

Read-only zeros

This struct is simply a read-only wrapper of Zeros.

• If you need a constant, you can make this struct directly from its constructor.
• Or you can use Zeros::read_only().

Examples

use std::convert::TryFrom;
use zeros::{ReadOnlyZeros, Zeros};

const SOME_HASH: ReadOnlyZeros = ReadOnlyZeros(Zeros::Z128([
    0xb2, 0xc2, 0x5d, 0x4b, 0x26, 0xd9, 0xfc, 0xb0,
    0xb3, 0x6f, 0xc9, 0xdf, 0x33, 0xb2, 0x8b, 0x46,
]));

// Zeros implements AsRef<[u8]> and TryFrom<&[u8]>
let another_hash = Zeros::try_from(SOME_HASH.as_ref())?;
assert_eq!(SOME_HASH, another_hash);
assert_eq!(SOME_HASH.to_string(), another_hash.to_string());
assert_eq!(SOME_HASH, another_hash.read_only());

Methods from Deref<Target = Zeros>

pub fn len(&self) -> usize

Gets number of bytes

pub fn same_class(&self, other: &Self) -> bool

Checks if this instance is same class as one other

Examples

use zeros::Zeros;

assert!(Zeros::from([0; 16]).same_class(&Zeros::from([0; 32])) == false);
assert!(Zeros::from([6; 48]).same_class(&Zeros::from([9; 48])));
