Struct kangarootwelve_xkcp::OutputReader

pub struct OutputReader(_);

An incremental reader for extended output, returned by Hasher::finalize_xof and Hasher::finalize_custom_xof.

Methods

impl OutputReader

pub fn squeeze(&mut self, buf: &mut [u8])

Fill a buffer with output bytes and advance the position of the OutputReader. This is equivalent to Read::read, except that it doesn't return a Result. Both methods always fill the entire buffer.

Trait Implementations

impl Clone for OutputReader

fn clone(&self) -> OutputReader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OutputReader

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

Formats the value using the given formatter.

impl Read for OutputReader

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

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

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

Read the exact number of bytes required to fill buf.

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

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.
