Struct ssb_crypto::Hash

#[repr(C)]pub struct Hash(pub [u8; 32]);

A sha256 hash digest. The standard hash in the scuttleverse.

Implementations

impl Hash

pub const SIZE: usize

The size in bytes of the Hash type ( == 32).

pub fn from_slice(s: &[u8]) -> Option<Self>

Deserialize from byte representation. Returns None if the slice length isn't 32. Note that this doesn't hash the provided byte slice, use the hash function for that.

pub fn from_base64(s: &str) -> Option<Self>

Deserialize from base-64 string representation. Ignores optional leading '%' or '&' sigil and '.sha256' suffix.

Example

let s = "%4hUgS4j0TwKdsZzOV/tfqiPtqoLw2qYg/Wl9Xy8FPEU=.sha256";
let h = ssb_crypto::Hash::from_base64(s).unwrap();

Trait Implementations

impl PartialEq<Hash> for Hash

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
