Struct tink_streaming_aead::subtle::noncebased::Writer

pub struct Writer { /* private fields */ }

Writer provides a framework for ingesting plaintext data and writing encrypted data to the wrapped io::Write. The scheme used for encrypting segments is specified by providing a SegmentEncrypter implementation.

Implementations

impl Writer

pub fn new(params: WriterParams) -> Result<Writer, TinkError>

Create a new Writer instance.

Trait Implementations

impl Drop for Writer

Manual Drop implementation which ensures the stream is closed.

fn drop(&mut self)

Executes the destructor for this type.

impl EncryptingWrite for Writer

fn close(&mut self) -> Result<(), TinkError>

Close the stream, writing any final buffered data. Any operation on the stream after this will fail.

impl Write for Writer

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

Flushing an encrypting writer does nothing even when there is buffered plaintext, because only complete segments can be written.

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

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

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, fmt: Arguments<'_>) -> Result<(), Error>

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

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

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