Struct protobuf::CodedOutputStream

pub struct CodedOutputStream<'a> { /* private fields */ }

Buffered write with handy utilities

Implementations

impl<'a> CodedOutputStream<'a>

pub fn new(writer: &'a mut dyn Write) -> CodedOutputStream<'a>

Construct from given Write.

CodedOutputStream is buffered even if Write is not

pub fn bytes(bytes: &'a mut [u8]) -> CodedOutputStream<'a>

CodedOutputStream which writes directly to bytes.

Attempt to write more than bytes capacity results in error.

pub fn vec(vec: &'a mut Vec<u8>) -> CodedOutputStream<'a>

CodedOutputStream which writes directly to Vec<u8>.

Caller should call flush at the end to guarantee vec contains all written data.

Trait Implementations

impl<'a> Write for CodedOutputStream<'a>

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 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 Selfwhere Self: Sized,

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