Implementations

impl Digest

pub const fn new(data: [u32; 8]) -> Digest

Create a new Digest from an existing array of words.

pub fn try_from_slice(words: &[u32]) -> Result<Digest, Error>

Try to create a Digest from a slice of words.

pub fn try_from_bytes(bytes: &[u8]) -> Result<Digest, Error>

Try to create a Digest from a slice of bytes.

pub fn from_slice(words: &[u32]) -> Digest

Create a Digest from a slice of words.

Panics

Panics if the number of words is not exactly DIGEST_WORDS.

pub fn from_bytes(bytes: &[u8]) -> Digest

Create a Digest from a slice of bytes.

Panics

Panics if the number of bytes is not exactly [DIGEST_WORDS] * [DIGEST_WORD_SIZE].

pub fn as_slice(&self) -> &[u32]

Returns a slice of words.

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

Returns a slice of bytes.

pub fn as_mut_slice(&mut self) -> &mut [u32]

Returns a mutable slice of words.

pub fn get(&self) -> &[u32; 8]

Returns an array of words.

pub fn get_mut(&mut self) -> &mut [u32; 8]

pub fn to_hex(&self) -> String

Returns a hexadecimal string representation of the Digest.

pub fn from_str(s: &str) -> Digest

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Digest

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Digest

fn default() -> Digest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Digest

fn deserialize<__D>(
    __deserializer: __D
) -> Result<Digest, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'zeroio_deserialize> Deserialize<'zeroio_deserialize> for Digest

type RefType = DigestRef<'zeroio_deserialize>

const FIXED_WORDS: usize = 8usize

fn deserialize_from(
    _buf: &'zeroio_deserialize [u32]
) -> <Digest as Deserialize<'zeroio_deserialize>>::RefType

fn from_ref(
    _val: &<Digest as Deserialize<'zeroio_deserialize>>::RefType
) -> Digest

impl Display for Digest

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<&[u8]> for Digest

fn from(bytes: &[u8]) -> Digest

Converts to this type from the input type.

impl From<&Digest> for Digest

fn from(digest: &Digest) -> Digest

Converts to this type from the input type.

impl From<&str> for Digest

fn from(s: &str) -> Digest

Converts to this type from the input type.

impl PartialEq<Digest> for Digest

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

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

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

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

impl Serialize for Digest

fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

    &self,
    _buf: &mut AllocBuf<'_>,
    _a: &mut Alloc<'_>
) -> Result<(), ZeroioError>

impl Zeroable for Digest

fn zeroed() -> Self

Calls zeroed.
