Struct HashFunctionWrapper 

pub struct HashFunctionWrapper<Variant, const DIGEST_LEN: usize>(/* private fields */);

This wraps a digest::Digest as a HashFunction.

Trait Implementations

impl<Variant: Default, const DIGEST_LEN: usize> Default for HashFunctionWrapper<Variant, DIGEST_LEN>

fn default() -> HashFunctionWrapper<Variant, DIGEST_LEN>

Returns the “default value” for a type.

impl<Variant: Digest + Default, const DIGEST_LEN: usize> HashFunction<DIGEST_LEN> for HashFunctionWrapper<Variant, DIGEST_LEN>

fn update<Data: AsRef<[u8]>>(&mut self, data: Data)

Process the given data, and update the internal of the hash function.

fn finalize(self) -> Digest<DIGEST_LEN>

Retrieve result and consume hash function.

const OUTPUT_SIZE: usize = DIGEST_LENGTH

The length of this hash functions digests in bytes.

fn new() -> Self

Create a new hash function of the given type

fn digest<Data: AsRef<[u8]>>(data: Data) -> Digest<DIGEST_LENGTH>

Compute the digest of the given data and consume the hash function.

fn digest_iterator<K: AsRef<[u8]>, I: Iterator<Item = K>>( iter: I, ) -> Digest<DIGEST_LENGTH>

Compute a single digest from all slices in the iterator in order and consume the hash function.

impl<Variant: CoreProxy + OutputSizeUser, const DIGEST_LEN: usize> ReverseWrapper for HashFunctionWrapper<Variant, DIGEST_LEN>

type Variant = Variant

impl<Variant: Digest + Default, const DIGEST_LEN: usize> Write for HashFunctionWrapper<Variant, DIGEST_LEN>

fn write(&mut self, buf: &[u8]) -> Result<usize>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.
