Struct protobuf_native::io::SliceOutputStream

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

A ZeroCopyOutputStream specialized for writing to byte slices.

Using this type is more efficient than using a WriterStream when the underlying writer is a type that exposes a simple mutable byte slice.

Implementations

impl<'a> SliceOutputStream<'a>

pub fn new(slice: &mut [u8]) -> Pin<Box<SliceOutputStream<'a>>>

Creates a new SliceOutputStream from the provided byte slice.

Trait Implementations

impl<'a> Drop for SliceOutputStream<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> ZeroCopyOutputStream for SliceOutputStream<'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.
