pub struct PreEncode<E> { /* private fields */ }
Expand description

method is called.
This is created by calling EncodeExt::pre_encode
method.

Source§fn encode_to_write_buf<B>(&mut self, buf: &mut WriteBuf<B>) -> Result<()>

Encodes the items remaining in the encoder and
writes the encoded bytes to the given write buffer.
Source§fn encode_to_write_buf_async<B>(
&mut self,
buf: &mut WriteBuf<B>,
cx: &mut Context<'_>,

fn encode_to_write_buf_async<B>( &mut self, buf: &mut WriteBuf<B>, cx: &mut Context<'_>, ) -> Result<()>
Encodes the items remaining in the encoder and
writes the encoded bytes to the given write buffer.
If the write buffer is full and the writing cannot be performed,
the given WriteBuf will memorize cx’s
Waker
.
This Waker
’s wake
will later be called when the WriteBuf
regains its free space.
