Struct Engine

pub struct Engine { /* private fields */ }

Engine to compute the SipHash24 hash function.

Implementations

impl Engine

pub const fn with_keys(k0: u64, k1: u64) -> Engine

Creates a new SipHash24 engine with keys.

pub const fn new() -> Engine

Creates a new SipHash24 engine.

pub fn keys(&self) -> (u64, u64)

Retrieves the keys of this engine.

Trait Implementations

impl Clone for Engine

fn clone(&self) -> Engine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Engine

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

Formats the value using the given formatter.

impl Default for Engine

fn default() -> Self

Returns the “default value” for a type.

impl HashEngine for Engine

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

Add bytes to the hash engine.

const BLOCK_SIZE: usize = 32usize

Length of the hash’s internal block size, in bytes.

type Digest = [u8; 8]

The digest returned by this hash engine.

type Midstate = State

Byte array representing the internal state of the hash engine.

fn n_bytes_hashed(&self) -> usize

Return the number of bytes already n_bytes_hashed(inputted).

fn finalize(self) -> Self::Digest

Returns the final digest from the current state of the hash engine.

fn midstate(&self) -> State

Outputs the midstate of the hash engine. This function should not be used directly unless you really know what you’re doing.

fn from_midstate(midstate: Self::Midstate, _length: usize) -> Engine

Create a new HashEngine from a Self::Midstate.

fn new() -> Self

Creates a new hash engine.

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

Creates a default hash engine, adds bytes to it, then finalizes the engine.

fn hash_byte_chunks<B, I>(byte_slices: I) -> Self::Digest

where B: AsRef<[u8]>, I: IntoIterator<Item = B>,

Hashes all the byte slices retrieved from the iterator together.

impl Write for Engine

Available on crate feature bitcoin-io only.

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.

impl Write for Engine

Available on crate feature bitcoin-io only.

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

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

Attempts to write an entire buffer into this writer.
