Struct protobuf_native::io::VecOutputStream

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

A ZeroCopyOutputStream specialized for writing to byte vectors.

Using this type is more efficient than using a WriterStream when the underlying writer is a byte vector.

Implementations

impl<'a> VecOutputStream<'a>

pub fn new(vec: &mut Vec<u8>) -> Pin<Box<VecOutputStream<'a>>>

Creates a new VecOutputStream from the provided byte vector.

Trait Implementations

impl<'a> Drop for VecOutputStream<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a> ZeroCopyOutputStream for VecOutputStream<'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.
