Implementations

impl<W: Write> EncrypterWriter<W>

pub fn new(
    writer: W,
    method: EncryptionMethod,
    key: &[u8],
    iv: Iv
) -> Result<EncrypterWriter<W>>

pub fn finalize(&mut self) -> W

Finalize the internal writer and encrypter and return the writer.

fn do_finalize(&mut self) -> Option<W>

impl EncrypterWriter<File>

pub fn sync_all(&self) -> IoResult<()>

Trait Implementations

impl<W: Write> Drop for EncrypterWriter<W>

fn drop(&mut self)

Executes the destructor for this type.

impl<W: Write> Write for EncrypterWriter<W>

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

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

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

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

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

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

pub 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.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

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

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