Struct Encryptor 

pub struct Encryptor<W: Write> { /* private fields */ }

An encrypting stream adapter that encrypts what is written to it.

write::Encryptor is a stream adapter that sits atop a Write stream. Plaintext written to the Encryptor is encrypted and written to the underlying stream.

Implementations

impl<W: Write> Encryptor<W>

pub fn new( writer: W, cipher: Cipher, key: &[u8], iv: &[u8], ) -> Result<Self, ErrorStack>

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

Finishes writing to the underlying cryptostream, padding the final block as needed, flushing all output. Returns the wrapped Write instance.

Trait Implementations

impl<W: Write> Write for Encryptor<W>

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

Writes decrypted bytes to the cryptostream, causing their encrypted contents to be written to the underlying Write object.

fn flush(&mut self) -> Result<(), Error>

Flushes the underlying stream but does not clear all internal buffers or explicitly pad the output blocks as that would prevent us from appeding anything in the future if we are not a block boundary.

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.
