Struct U32BE

pub struct U32BE;

Codec for an u32 big-endian.

Examples

Decoding

let mut decoder = U32BE::default();

let res = decoder.decode(&mut BytesMut::from("\x2A\x3B\x4C\x5D")).unwrap();

assert_eq!(res, Some(0x2A3B4C5D))

Encoding

let mut encoder = U32BE::default();

let mut dst = BytesMut::default();
encoder.encode(0x2A3B4C5D, &mut dst).unwrap();

assert_eq!(dst, BytesMut::from("\x2A\x3B\x4C\x5D"))

Trait Implementations

impl Debug for U32BE

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

Formats the value using the given formatter.

impl Decoder for U32BE

type Item = u32

The type of decoded frames.

type Error = Error

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 U32BE

fn default() -> U32BE

Returns the “default value” for a type.

impl Encoder<u32> for U32BE

type Error = Error

The type of encoding errors.

fn encode(&mut self, item: u32, dst: &mut BytesMut) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.
