impl Write for Sha512Trunc256[+]

[+] Show hidden undocumented items

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

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

fn flush(&mut self) -> Result<()>[−]

Flush 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 Writeer 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" adaptor for this instance of Write.
