Struct Chacha

pub struct Chacha<W>
where
    W: Write,
{ /* private fields */ }

Available on little-endian only.

Chacha

You can make new instance via Variant.

Implementations

impl<W> Chacha<W>

where W: Write,

pub const fn variant(&self) -> &Variant

Gets variant

pub fn encrypt<B>(&mut self, bytes: B) -> Result<usize>

where B: AsRef<[u8]>,

Encrypts new bytes

This function always returns your data’s size, but it does NOT always write your whole data out. It’s because encrypting works only on blocks of a fixed size. Exceeded data will be kept in an internal buffer. That buffer will be processed in finish().

pub fn encrypt_bytes<'a, const N: usize, B, B0>( &mut self, bytes: B, ) -> Result<Option<usize>>

where B: Into<Bytes<'a, N, B0>>, B0: AsRef<[u8]> + 'a,

Encrypts new data

Returns length of input bytes. If overflow happens, None will be returned.

See encrypt() for more details.

pub fn finish(self) -> Result<W>

Finishes and returns your output

Trait Implementations

impl<W> Debug for Chacha<W>

where W: Write + Debug,

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

Formats the value using the given formatter.

impl<W> Write for Chacha<W>

where W: Write,

Available on crate feature std only.

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

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

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

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.
