Struct bytecodec::io::WriteBuf [−][src]
pub struct WriteBuf<B> { /* fields omitted */ }
Expand description
Write buffer.
Implementations
Returns the free space of the buffer.
Invariant: self.len() + self.room() <= self.capacity()
Returns the state of the stream that operated in the last flush()
call.
Returns a mutable reference to the StreamState
instance.
Writes the encoded bytes contained in this buffer to the given writer.
The written bytes will be removed from the buffer.
The flush process continues until one of the following condition is satisfied:
- The write buffer became empty
- A write operation returned a
WouldBlock
error - The output stream has reached EOS
Returns a mutable reference to the inner bytes of the buffer.
Takes ownership of ReadBuf
and returns the inner bytes of the buffer.

pub fn poll_flush<W: AsyncWrite>(

) -> Poll<Result<()>>
Writes the encoded bytes contained in this buffer to the given writer.
The written bytes will be removed from the buffer.
The flush process continues until one of the following condition is satisfied:
- The write buffer became empty
