Struct bytecodec::fixnum::U24beDecoder

pub struct U24beDecoder(_);

Decoder which decodes unsigned 24-bit integers by big-endian byte order.

The type of decoded values is u32, but the most significant 8-bits always be 0.

Examples

use bytecodec::{Decode, DecodeBuf};
use bytecodec::fixnum::U24beDecoder;

let mut decoder = U24beDecoder::new();
let item = decoder.decode(&mut DecodeBuf::new(&[0x01, 0x02, 0x03][..])).unwrap();
assert_eq!(item, Some(0x0001_0203u32));

Methods

impl U24beDecoder

pub fn new() -> Self

Makes a new U24beDecoder instance.

Trait Implementations

impl Debug for U24beDecoder

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for U24beDecoder

fn default() -> U24beDecoder

Returns the "default value" for a type.

impl Decode for U24beDecoder

type Item = u32

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.
