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, DecodeBuf};
use bytecodec::fixnum::U48beDecoder;

let mut decoder = U48beDecoder::new();
let item = decoder.decode(&mut DecodeBuf::new(&[0x01, 0x02, 0x03, 0x04, 0x05, 0x06][..])).unwrap();
assert_eq!(item, Some(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, __arg_0: &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: &mut DecodeBuf) -> Result<Option<Self::Item>>

Consumes the given buffer (a part of a byte sequence), and decodes an item from it.

fn has_terminated(&self) -> bool

Returns true if the decoder cannot decode items anymore, otherwise false.

fn is_idle(&self) -> bool

Returns true if the decoder does not have an item that being decoded, otherwise false.

fn requiring_bytes_hint(&self) -> Option<u64>

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