Struct bytecodec::fixnum::U48beDecoder

pub struct U48beDecoder(_);

Decoder which decodes unsigned 48-bit integers by big-endian byte order.

The type of decoded values is u64, but the most significant 16-bits always be 0.

Examples

use bytecodec::Decode;
use bytecodec::fixnum::U48beDecoder;
use bytecodec::io::IoDecodeExt;

let mut decoder = U48beDecoder::new();
let item = decoder.decode_exact([0x01, 0x02, 0x03, 0x04, 0x05, 0x06].as_ref()).unwrap();
assert_eq!(item, 0x0000_0102_0304_0506u64);

Methods

impl U48beDecoder

pub fn new() -> Self

Makes a new U48beDecoder instance.

Trait Implementations

impl Debug for U48beDecoder

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

Formats the value using the given formatter.

impl Default for U48beDecoder

fn default() -> U48beDecoder

Returns the "default value" for a type.

impl Decode for U48beDecoder

type Item = u64

The type of items to be decoded.

fn decode(&mut self, buf: &[u8], eos: Eos) -> Result<usize>

Consumes the given buffer (a part of a byte sequence), and proceeds the decoding process.

fn finish_decoding(&mut self) -> Result<Self::Item>

Finishes the current decoding process and returns the decoded item.

fn requiring_bytes(&self) -> ByteCount

Returns the lower bound of the number of bytes needed to decode the next item.

fn is_idle(&self) -> bool

Returns true if there are no items to be decoded by the decoder at the next invocation of decode method, otherwise false.
