Struct Digest 

#[repr(transparent)]
pub struct Digest(pub [u8; 32]);

Common digest type for the gsigner ecosystem. Presently, it is represented as 32-byte Keccak256 hash. The ToDigest trait is implemented for various types to facilitate hashing and signing.

Tuple Fields

0: [u8; 32]

Implementations

impl Digest

pub const fn zero() -> Digest

pub fn random() -> Digest

NOTE: This function is cryptographically insecure and should not be used in production.

impl EncodeLike for Digest

impl Eq for Digest

impl<'a> From<&'a Digest> for Digest

fn from(digest: &'a Digest) -> Digest

Converts to this type from the input type.

impl<T> From<T> for Digest

where T: ToDigest,

fn from(item: T) -> Digest

Converts to this type from the input type.

Creates a value from an iterator.

impl Hash for Digest

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Digest

fn cmp(&self, other: &Digest) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

impl PartialEq for Digest

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
