Struct protobuf_native::io::WriterStream

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

Converts an Write implementor to a ZeroCopyOutputStream.

Implementations

impl<'a> WriterStream<'a>

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

Creates a writer stream from the specified Write implementor.

Trait Implementations

impl<'a> Drop for WriterStream<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> ZeroCopyOutputStream for WriterStream<'a>

unsafe fn next( self: Pin<&mut Self>, ) -> Result<&mut [MaybeUninit<u8>], OperationFailedError>

Obtains a buffer into which data can be written.

fn back_up(self: Pin<&mut Self>, count: usize)

Backs up a number of bytes, so that the end of the last buffer returned by next is not actually written.

fn byte_count(&self) -> i64

Returns the total number of bytes written since this object was created.
