Struct RtuCodec 

pub struct RtuCodec;

RTU codec for serial Modbus framing.

Frame boundaries are determined by inter-character silence (handled by the transport layer). This codec validates CRC and extracts the PDU.

Trait Implementations

impl Debug for RtuCodec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decoder for RtuCodec

type Item = Frame

The type of decoded frames.

type Error = FrameError

The type of unrecoverable frame decoding errors.

fn decode( &mut self, src: &mut BytesMut, ) -> Result<Option<Self::Item>, Self::Error>

Attempts to decode a frame from the provided buffer of bytes.

fn decode_eof( &mut self, buf: &mut BytesMut, ) -> Result<Option<Self::Item>, Self::Error>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self>

where T: AsyncRead + AsyncWrite, Self: Sized,

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

impl Default for RtuCodec

fn default() -> RtuCodec

Returns the “default value” for a type.

impl Encoder<Frame> for RtuCodec

type Error = FrameError

The type of encoding errors.

fn encode(&mut self, item: Frame, dst: &mut BytesMut) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.
