Struct ntex::codec::Framed [−][src]
pub struct Framed<T, U> { /* fields omitted */ }
Expand description
A unified interface to an underlying I/O object, using
the Encoder
and Decoder
traits to encode and decode frames.
Framed
is heavily optimized for streaming io.

T: AsyncRead + AsyncWrite,
U: Decoder + Encoder,
[src]
impl<T, U> Framed<T, U> where
T: AsyncRead + AsyncWrite,
U: Decoder + Encoder,
[src]pub fn new(io: T, codec: U) -> Framed<T, U>
[src]
pub fn new(io: T, codec: U) -> Framed<T, U>
[src]Provides an interface for reading and writing to
Io
object, using Decode
and Encode
traits of codec.
Raw I/O objects work with byte sequences, but higher-level code usually
wants to batch these into meaningful chunks, called “frames”. This
method layers framing on top of an I/O object, by using the Codec
traits to handle encoding and decoding of messages frames. Note that
the incoming and outgoing frame types may be distinct.
