Struct EncryptBufWriter 

pub struct EncryptBufWriter<A, B, W, S>
where
    A: AeadInPlace,
    B: CappedBuffer,
    W: Write,
    S: StreamPrimitive<A>,
    A::NonceSize: Sub<S::NonceOverhead>,
    NonceSize<A, S>: ArrayLength<u8>,
{ /* private fields */ }

A wrapper around a Write object and a StreamPrimitive providing a Write interface which automatically encrypts the underlying stream when writing

Implementations

impl<A, B, W, S> EncryptBufWriter<A, B, W, S>

where A: AeadInPlace, B: CappedBuffer, W: Write, S: StreamPrimitive<A>, A::NonceSize: Sub<S::NonceOverhead>, NonceSize<A, S>: ArrayLength<u8>,

pub fn new( key: &Key<A>, nonce: &Nonce<A, S>, buffer: B, writer: W, ) -> Result<Self, InvalidCapacity>

where A: KeyInit, S: NewStream<A>,

Constructs a new Writer using an AEAD key, buffer and reader

pub fn from_aead( aead: A, nonce: &Nonce<A, S>, buffer: B, writer: W, ) -> Result<Self, InvalidCapacity>

where A: KeyInit, S: NewStream<A>,

Constructs a new Writer using an AEAD primitive, buffer and reader

pub fn inner(&self) -> &W

Gets a reference to the inner writer

pub fn into_inner(self) -> Result<W, IntoInnerError<Self, W::Error>>

Consumes the Writer and returns the inner writer

Trait Implementations

impl<A, B, W, S> Drop for EncryptBufWriter<A, B, W, S>

where A: AeadInPlace, B: CappedBuffer, W: Write, S: StreamPrimitive<A>, A::NonceSize: Sub<S::NonceOverhead>, NonceSize<A, S>: ArrayLength<u8>,

fn drop(&mut self)

Executes the destructor for this type.

impl<A, B, W, S> Write for EncryptBufWriter<A, B, W, S>

where A: AeadInPlace, B: CappedBuffer, W: Write, W::Error: Into<Error>, S: StreamPrimitive<A>, A::NonceSize: Sub<S::NonceOverhead>, NonceSize<A, S>: ArrayLength<u8>,

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.
