Enum HashAlgorithm 

pub enum HashAlgorithm {
    Sha1(Sha1),
    Sha256(Sha256),
}

a hash abstraction to support both SHA1 and SHA256 which for stream hashing handle use (e.g. Sha1::new()) std::io::Write trait to update the hash state

Variants

Sha1(Sha1)

Sha256(Sha256)

Implementations

impl HashAlgorithm

pub fn update(&mut self, data: &[u8])

Update hash with data

pub fn finalize(self) -> Vec<u8>

Finalize and get hash result

pub fn new() -> Self

Create a new hash algorithm instance based on the current hash kind.

Trait Implementations

impl Clone for HashAlgorithm

fn clone(&self) -> HashAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for HashAlgorithm

fn default() -> Self

Returns the “default value” for a type.

impl Write for HashAlgorithm

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.
