Struct bytecodec::fixnum::U48beEncoder

pub struct U48beEncoder(_);

Encoder which encodes unsigned 48-bit integers by big-endian byte order.

Although the type of items is u64, the most significant 16-bits must be 0.

Examples

use bytecodec::EncodeExt;
use bytecodec::fixnum::U48beEncoder;
use bytecodec::io::IoEncodeExt;

let mut output = Vec::new();
let mut encoder = U48beEncoder::with_item(0x0000_0102_0304_0506).unwrap();
encoder.encode_all(&mut output).unwrap();
assert_eq!(output, [0x01, 0x02, 0x03, 0x04, 0x05, 0x06]);

Implementations

impl U48beEncoder

pub fn new() -> Self

Makes a new U48beEncoder integers.

Trait Implementations

impl Debug for U48beEncoder

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

Formats the value using the given formatter.

impl Default for U48beEncoder

fn default() -> U48beEncoder

Returns the “default value” for a type.

impl Encode for U48beEncoder

type Item = u64

The type of items to be encoded.

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

Encodes the items in the encoder and writes the encoded bytes to the given buffer.

fn start_encoding(&mut self, item: Self::Item) -> Result<()>

Tries to start encoding the given item.

fn requiring_bytes(&self) -> ByteCount

Returns the number of bytes required to encode all the items in the encoder.

fn is_idle(&self) -> bool

Returns true if there are no items to be encoded in the encoder, otherwise false.

impl SizedEncode for U48beEncoder

fn exact_requiring_bytes(&self) -> u64

Returns the exact number of bytes required to encode all the items remaining in the encoder.
